What is Medicare Advantage?

Medicare Advantage, also called Part C, is offered by private insurance companies approved by Medicare. It usually combines Part A, Part B, and often Part D prescription drug coverage.

What is the difference between Original Medicare and Medicare Advantage?

Original Medicare is run by the federal government and lets you use any provider that accepts Medicare. Medicare Advantage is offered by private insurers and often uses provider networks.

What is Medicare Supplement or Medigap?

Medicare Supplement, also called Medigap, works with Original Medicare to help reduce out-of-pocket costs. It can help cover certain copays, coinsurance, and deductibles.

Does Medigap include prescription drug coverage?

Medigap plans sold today do not include prescription drug coverage. Most people need a separate Medicare Part D plan for medications.

What is Medicare Part D?

Medicare Part D is prescription drug coverage offered by private insurance companies approved by Medicare. It helps cover medication costs based on the plan’s formulary.

When is the Medicare Annual Enrollment Period?

The Medicare Annual Enrollment Period usually runs from October 15 to December 7 each year. During this time, many people can review or change Medicare Advantage and Part D plans.

Can I switch Medicare Advantage plans later?

Yes, but timing matters. Most people can switch during Annual Enrollment, Medicare Advantage Open Enrollment, or a qualifying Special Enrollment Period.

What is the difference between HMO and PPO Medicare Advantage plans?

HMO plans usually require in-network care and may need referrals. PPO plans generally offer more provider flexibility but may cost more for out-of-network care.

Do Medicare Advantage plans require prior authorization?

Many Medicare Advantage plans require prior authorization for certain services. This can include imaging, surgeries, skilled nursing care, or other covered treatments.

Do Medicare Advantage plans have an out-of-pocket limit?

Yes, Medicare Advantage plans include an annual maximum out-of-pocket limit for covered medical services. Original Medicare does not include this protection by itself.

Why do Medicare plans change every year?

Plans may update premiums, copays, drug formularies, provider networks, and benefits each year. Reviewing your plan annually helps avoid unexpected changes.

How can I find a Medicare plan that includes my doctor?

You should check the plan’s provider network before enrolling. A local Medicare agent can help confirm whether your doctors and hospitals are included.

IRMAA is an income-related adjustment that can increase Medicare Part B and Part D premiums. It is based on your reported income from prior tax years.

What is a Special Enrollment Period?

A Special Enrollment Period allows certain Medicare changes outside normal enrollment windows. Qualifying events may include moving, losing coverage, or plan changes.

Why work with a local Medicare agent?

A local Medicare agent can help compare plan options, explain networks, and review coverage based on your area. This can make Medicare decisions easier to understand.

Choosing the Right Medicare Coverage: A Friendly Guide

May 12, 2025

Choosing a Medicare plan can feel overwhelming – so many parts and plans! 😵 But don’t worry. In this friendly guide, we’ll break down the basics of Medicare (Parts A, B, C, and D), explore the pros and cons of different coverage options (Original Medicare vs. Medicare Advantage, plus how Medigap fits in), and share some handy shopping tips. By the end, you should feel more comfortable choosing the Medicare coverage that fits you best – just as if a good friend explained it over coffee. ☕️

Medicare Basics: Understanding the Alphabet Soup

Medicare is divided into “Parts” – think of them as pieces of your healthcare puzzle. Here’s a quick overview of what each part covers and how they work together:

Infographic: The ABCDs of Medicare – Parts A, B, C, and D at a glance. Parts A and B make up Original Medicare, Part C is Medicare Advantage (a private plan alternative), and Part D is prescription drug coverage.

Part A – Hospital Insurance: Covers inpatient hospital stays, skilled nursing facility care, hospice care, and some home health care. Most people don’t pay a premium for Part A if they or their spouse paid Medicare taxes while working.
Part B – Medical Insurance: Covers doctor visits, outpatient care, preventive services (like screenings and vaccines), and medical equipment (wheelchairs, walkers, etc.). Part B has a monthly premium (standard $174.70/month in 2024, rising to $185.00 in 2025 for most folks) and you typically pay 20% coinsurance for services after a small annual deductible.
Part C – Medicare Advantage: An “all-in-one” alternative to Original Medicare offered by private insurance companies. These plans bundle Part A + Part B (and usually Part D for drugs) into one plan. Medicare Advantage plans often include extra benefits like dental, vision, hearing, or gym memberships that Original Medicare doesn’t cover. We’ll discuss these in detail soon.
Part D – Prescription Drug Coverage: Helps pay for your medications. You can get Part D by joining a standalone drug plan (if you have Original Medicare) or through a Medicare Advantage plan that includes drug coverage (most do). Part D plans are offered by private insurers under Medicare’s rules, and each plan has its own list of covered drugs (formulary) and pharmacy network.

Original Medicare (Parts A & B)

Original Medicare is the traditional program directly run by the federal government. It includes Part A (hospital) and Part B (medical) coverage. Here’s what it means for you:

Broad Provider Choice: With Original Medicare, you can go to any doctor or hospital nationwide that accepts Medicare – no networks, no referrals needed in most cases. This is great if you want flexibility to choose or if you travel around the U.S.
What Original Medicare Covers: Part A covers inpatient needs (hospital stays, rehab in a skilled nursing facility, hospice, etc.), and Part B covers outpatient needs (doctor visits, tests, procedures, emergency room, preventive care and more). Together, Parts A and B cover most medically necessary services. However, Original Medicare does NOT cover some routine services, like most dental care, eye exams for glasses, hearing aids, or long-term custodial care.
Costs (and the “Gaps”): You pay a Part B premium (and Part A premium is free for most). When you use services, Medicare generally pays 80% of the approved amount for Part B services and you pay the remaining 20% (coinsurance) after meeting the deductible. Importantly, there is no annual limit on your out-of-pocket costs with Original Medicare alone. This is one of the biggest “gaps” – meaning if you have a serious health issue, that 20% could be significant with no cap. Many people address this by adding a Medigap supplement to help pay those costs (more on Medigap below).
Drug Coverage: Original Medicare by itself doesn’t include prescription drug coverage, so you’d typically enroll in a separate Part D drug plan if you need medication coverage. (Don’t skip Part D if you have no other drug coverage, because going without it could lead to a late enrollment penalty later!)
Using Medigap: With Original Medicare, you have the option to buy a Medigap policy (Medicare Supplement Insurance) from a private insurer. Medigap plans are standardized (labeled Plan A, B, C, D, F, G, etc.) and they help pay for the cost-sharing that Original Medicare leaves you with – like that 20% coinsurance, hospital deductibles, and so on. For example, most Medigap plans cover all or most of your Part A & B deductibles and coinsurance (Plan G is a popular choice for new enrollees that covers almost everything except the Part B deductible). The result is you pay an extra premium for Medigap, but your out-of-pocket expenses can be dramatically lower and more predictable.

💡 Friendly tip: The best time to buy a Medigap policy is during your initial 6-month Medigap Open Enrollment Period (when you’re 65+ and have Part B) – during this time, you can get any Medigap plan without health underwriting or being denied for pre-existing conditions. If you try to enroll in Medigap later, insurers can generally charge you more or deny coverage based on your health in most states. So, plan ahead if you want that supplemental coverage safety net.

Foreign Travel: Original Medicare provides very limited coverage outside the U.S. – generally it won’t cover you abroad except in a few rare situations. Some Medigap plans, however, do cover emergency care during foreign travel (typically 80% of costs up to a limit). If international travel is in your retirement plans, keep this in mind.

In summary, Original Medicare gives you wide freedom in choosing providers and is straightforward in what it covers. But it doesn’t cover everything (no routine dental/vision, no drugs by itself), and without a Medigap supplement you’re exposed to potentially high out-of-pocket costs since there’s no cap on your share. Many people on Original Medicare therefore mix and match Parts A + B + D, and often add a Medigap plan, to create comprehensive coverage. It’s a bit like an à la carte approach: you assemble the pieces you need (hospital, medical, drug, supplement).

Now, let’s talk about the alternative – Medicare Advantage – which packages everything into one plan.

Medicare Advantage (Part C)

Medicare Advantage, or Part C, is an “all-in-one” option offered by private insurance companies that are approved by Medicare. When you join a Medicare Advantage Plan, you still have Medicare, but you’ll get your Part A (hospital) and Part B (medical) coverage through the private plan instead of directly through Original Medicare. Here’s the scoop on Advantage plans:

All-in-One Coverage: A typical Medicare Advantage plan bundles Part A + Part B + Part D (drug coverage) together. Most plans also include extra benefits that Original Medicare doesn’t cover, such as dental, vision, hearing aids, and wellness programs (like gym memberships). It’s convenient to have one card and one plan for all your healthcare needs.

Different Types of Plans: Medicare Advantage plans can be HMOs, PPOs, or other types. In an HMO, you generally must use the plan’s network doctors and hospitals (and need a referral to see specialists). PPOs offer more flexibility – you can go out-of-network, but it costs more, and usually you don’t need referrals. There are also Special Needs Plans and others, but the main idea is each plan has rules about how you access care.

Network and Provider Choice: Unlike Original Medicare, **Medicare Advantage **plans typically have a network of doctors, hospitals, and pharmacies. You’ll usually need to use providers in that network for the plan to cover your care (except emergencies). For example, an HMO plan might require you to see in-network doctors and get a referral from your primary doctor to see a specialist. If you go outside the network, you could be paying significantly more, or the plan might not cover the service at all (except urgent or emergency care). This means your choice of doctors is more limited with Advantage – it’s ideal if you’re okay with the doctors and hospitals in the plan’s network, but it can be a drawback if you have specific providers you want to keep who aren’t in-network.

Costs and Out-of-Pocket Limits: With Medicare Advantage, you still pay your Part B premium each month (that doesn’t go away). Many Advantage plans have an additional monthly premium on top of that, but there are also many $0 premium Advantage plans available in most areas (insurers get paid by Medicare to provide your care, allowing some plans to charge you nothing extra per month). Keep in mind, “$0 premium” doesn’t mean $0 cost – you’ll pay copays or coinsurance for services as you go.

Every Medicare Advantage plan has an annual out-of-pocket maximum (OOP cap) for Part A and B services – a financial safety net. Once your copays/coinsurance reach that cap, the plan pays 100% of covered services for the rest of the year. For example, in 2024 the maximum OOP allowed for Advantage plans is $8,850 (and up to $9,350 in 2025) for in-network care, though many plans set their limits lower. This is a key advantage of Advantage plans: you have a cap on expenses, whereas Original Medicare alone has no cap.

On the other hand, you’ll typically be responsible for various deductibles, copays, or coinsurance for services in an Advantage plan. For instance, you might pay $20 for a primary care visit, $50 for a specialist, a certain copay per day for hospital stays, etc., until you hit that OOP max. Also, if your plan includes drug coverage, your drug costs (copays for prescriptions) usually do NOT count toward the medical out-of-pocket max (drug plans have their own cost structure including a possible coverage gap, but that’s another story).

Extra Benefits: Medicare Advantage plans often shine in offering benefits beyond medical insurance. The majority of plans include at least some dental, vision, and hearing coverage, which Original Medicare doesn’t cover at all. Many plans also offer perks like free gym memberships (SilverSneakers or similar fitness programs), transportation to medical appointments, over-the-counter item allowances, and more. If these benefits are important to you, an Advantage plan might be appealing.

Medigap and Supplementals:Important: You cannot use a Medigap supplemental plan with Medicare Advantage>. Medigap only works with Original Medicare. But that’s usually okay, because Advantage plans structure their own cost-sharing and have the out-of-pocket limit, so you wouldn’t need a Medigap. Just know that if you go the Advantage route, you’re generally locked into that plan’s cost structure for the year.

Geography and Travel: Medicare Advantage plans are regional. When you enroll, it’s typically for the area (county or state) where you live, and most plans only cover non-emergency care within their service area/network. If you’re out of state, or even out of your county, routine care might not be covered (unless you have a PPO with out-of-network coverage, and even then, you’ll pay more). However, emergency or urgent care is always covered nationwide at in-network cost levels – you won’t be stranded if you have an emergency while traveling in the U.S. That said, frequent travelers (or snowbirds splitting time in two states) often prefer Original Medicare for its nationwide flexibility. For foreign travel, Medicare Advantage is similar to Original: generally no coverage outside the U.S., except possibly emergency coverage in some plans or extra travel riders.

Prior Authorization and Plan Rules: Medicare Advantage plans can require prior authorization for certain procedures or services (meaning your doctor and plan must get approval from the plan before you get the service). This is more common in Advantage plans than in Original Medicare. It can add some paperwork or hoops to jump through for things like specialized treatments, scans, or elective procedures. Original Medicare rarely requires prior authorization for most services, whereas Advantage plans might require it for expensive medications, hospital stays, specialist visits, etc. This doesn’t mean you won’t get the care – it just means an extra step to confirm the plan will cover it.

In summary, Medicare Advantage is like a one-stop shop for your Medicare needs: one plan, often with extra perks, and a cap on costs. The trade-offs are you’ll have restricted provider networks, potential need for referrals/approvals, and less freedom to roam outside your plan’s network or area for routine care. Many people love the simplicity and lower monthly premiums (over half of Medicare beneficiaries have chosen Advantage as of 2023), while others prefer the flexibility of Original Medicare. The “right” choice depends on your priorities – which we’ll help clarify as we compare the two side by side next.

Medigap (Medicare Supplement Insurance)

Before we compare Original Medicare and Advantage directly, let’s clarify Medigap, since it’s an important piece if you consider staying with Original Medicare. Medigap policies are sold by private insurers to fill the “gaps” in Original Medicare. These standardized plans (with names like Plan G, Plan N, etc.) help pay for out-of-pocket costs like deductibles and that 20% coinsurance on Part B services.

If you have Original Medicare without Medigap, you’ll pay deductibles (e.g. the Part A hospital deductible, Part B’s annual deductible) and generally 20% of all your outpatient services, with no limit. With a Medigap plan, depending on the plan type, those costs can be partially or fully covered. For example, all Medigap plans cover the Part B 20% coinsurance (at least 100% of it after your deductible), and they all cover the Part A hospital coinsurance (the portion you’d owe after day 60 of a hospital stay) in full. Comprehensive Medigap plans like Plan F or Plan G can essentially eliminate most Medicare cost-sharing, meaning you’d pay little or nothing out-of-pocket for Medicare-approved services aside from your premiums.

You pay a monthly premium for Medigap in addition to your Part B (and Part D if you have one). The premium varies by plan type and your state/age – averaging about $150-$200/month for popular plans like G in many states (it can be less or more). So, Medigap means a higher fixed cost each month, but much lower unpredictable costs when you actually use care.

Medigap only works with Original Medicare. If you enroll in a Medicare Advantage plan, you cannot use Medigap to cover copays – in fact, it’s illegal for an insurer to sell you a Medigap if you have Advantage. Advantage plans have their own cost limits, so Medigap isn’t needed there.

We mentioned it earlier, but it bears repeating: you have guaranteed right to buy any Medigap without health screening in your first 6 months of Part B at age 65+. If you try to switch from Advantage to Original + Medigap later, you might have to answer health questions and could be declined or charged more (rules vary by state). Some folks will start with Original + Medigap at 65 to lock in that coverage, whereas if they started with Advantage for a few years and then want to switch to Medigap, they need to be mindful of this potential hurdle.

Think of Medigap as a way to get peace of mind with Original Medicare – you pay extra for the supplement, but you gain predictable costs and the ability to see any Medicare provider without worrying about copays. If you prefer paying more upfront (in premiums) to avoid big bills later, Medigap is worth considering. If the added premium is too expensive or you’re okay with some cost-sharing, you might skip Medigap (or choose a lower-coverage Medigap like Plan N with lower premiums). It’s all about your budget and risk comfort.

Alright, now that we’ve covered the components (Original Medicare Parts A/B, Part D, Medigap, and Medicare Advantage Part C), let’s put Original Medicare and Medicare Advantage head to head in a comparison. This will help highlight the key differences and help you decide which path might suit you better.

Original Medicare vs. Medicare Advantage: Key Differences

Both Original Medicare and Medicare Advantage cover the core services (hospital and medical), but they do so in different ways. Neither is inherently “better” for everyone – it truly depends on your needs and preferences. Let’s compare them on important factors like provider choice, costs, coverage extras, and more.

For an at-a-glance comparison, see the chart below comparing Original Medicare to Medicare Advantage:

From the above, here are some key points to note in comparing Original Medicare (Parts A & B) with Medicare Advantage (Part C):

Provider Choice & Networks: Original Medicare offers unrestricted provider choice – you can see any doctor or go to any hospital in the U.S. that accepts Medicare. There are over a million healthcare providers nationwide who accept Medicare, so it’s very broad. Medicare Advantage, on the other hand, generally limits you to its network of doctors/hospitals for non-emergency care. If you go out-of-network, you may have to pay full price (HMO) or higher cost (PPO). Bottom line: Choose Original Medicare if you want maximal freedom in choosing or if you live in/ravel to multiple areas; choose Advantage if you are okay sticking to a network (which might include many good providers in your area, but perhaps not all).

Referrals & Plan Rules: With Original Medicare, you usually do not need referrals to see specialists – you are your own “gatekeeper”. With many Medicare Advantage plans (especially HMOs), you’ll need a referral from your primary care doctor to see a specialist. Also, Advantage plans may require prior authorization for certain services more often. Translation for you: Original Medicare is generally simpler – go to any specialist when needed. Advantage plans might coordinate your care more tightly, which some people appreciate and others find restrictive.

Costs – Premiums vs. Out-of-Pocket: With Original Medicare, you pay the Part B premium (and Part A is usually free). If you add Medigap and Part D, those have premiums too. So your monthly premiums might be higher with Original+Medigap+PartD than an Advantage plan (which often has $0 or low premium aside from Part B). However, in exchange, Original Medicare (especially with Medigap) will have lower costs when you actually use care – you might pay almost nothing out-of-pocket at the doctor. Medicare Advantage typically offers lower or no additional premium but you will pay copays/coinsurance as you go. It also has an annual cap on those costs (protecting you from extremely high bills), whereas Original Medicare requires buying a Medigap for similar protection. So it’s a trade-off: pay more upfront every month vs. pay more when you need services.

Out-of-Pocket Limit: As mentioned, Original Medicare has no built-in out-of-pocket maximum – your 20% share just keeps accruing if you have a lot of medical bills. Only supplemental coverage (Medigap, Medicaid, employer retiree plan, etc.) can protect you there. Medicare Advantage includes an annual limit on your spending for Part A/B services. For example, if an Advantage plan’s OOP max is $5,000, once you’ve paid that much in copays in a year, the plan pays 100% of further Part A/B costs that year. Medicare requires these caps to ensure you’re not on the hook endlessly (again, max $9,350 in 2025, but many plans have lower limits). Consideration: If you worry about catastrophic costs and you don’t have/want Medigap, Advantage at least gives a safety net. If you have a good Medigap, you effectively have a safety net in Original Medicare too (since Medigap would cover the vast majority of costs).

Prescription Drugs: Original Medicare by itself doesn’t include drug coverage – you’d add a separate Part D plan. Medicare Advantage almost always includes Part D (about 90% of MA plans do), so most Advantage enrollees have their drug plan integrated. One less plan to juggle. However, each Advantage plan’s drug coverage is unique – formularies and pharmacy networks vary, so you’ll want to check your medications (more on that in Tips). If you prefer having everything in one plan, Advantage wins here.

Extra Benefits: This is a big selling point of Medicare Advantage. Dental, vision, hearing, hearing aids, eyeglasses, gym memberships, transportation, even some meal delivery or wellness programs – these are commonly offered by Advantage plans. Original Medicare doesn’t cover these, and Medigap generally doesn’t either (Medigap is strictly to cover cost-sharing, not extra services). You can always pay out-of-pocket or find separate insurance for things like dental if you stay with Original, but many Advantage plans bundle these perks at no extra cost. So if you really value, say, some basic dental coverage or a free gym membership, Advantage may be appealing.

Changing Plans:If you choose an Advantage plan and later change your mind, you can switch back to Original Medicare (and pick up a Part D plan) during the Medicare Open Enrollment Period each year (Oct 15 – Dec 7), or switch to another Advantage plan. However, switching into a Medigap later might require health screening (as noted). If you start with Original and Medigap, you can also switch to Advantage during fall enrollment. In either case, you’re not absolutely locked in forever – you have options to review coverage annually. In fact, it’s wise to review your plan every year because premiums, benefits, and formularies can change.

Enrollment & Admin: Minor point – to use Original Medicare, you enroll through Social Security/Medicare for Parts A and B, and separately sign up for any Part D or Medigap you want. With Advantage, you enroll in the private plan of your choice (which automatically links in your Medicare A/B benefits). With Original, you’ll use your red-white-and-blue Medicare card; with Advantage, you use the plan’s ID card when getting services. Either way, Medicare is overseeing your coverage – Advantage plans have to follow Medicare’s rules and cover all the same basic benefits as Original Medicare (they can’t skimp on core services). The difference is in how you pay and access care.

To put it in friend-to-friend terms: Original Medicare (especially with a Medigap) is like a premium buffet – you pay a higher entry fee (premiums), but then you can pick any doctor/hospital you want, as much as you need, often without paying at each visit. Medicare Advantage is like a pre-fixe menu at a restaurant – possibly cheaper to get in, and it might include dessert (dental/vision extras 😄), but you have to stick to the menu (network) and pay a bit each course (copays), with an assurance you won’t pay above a certain amount.

Neither approach is “one size fits all.” Next, we’ll go over some tips to help you choose which route – and which specific plan – might be best for you.

Tips for Choosing Your Medicare Plan

Everyone’s needs are different. As you think about your Medicare coverage choices, consider the following tips to make an informed decision:

✔️ Use Medicare’s Plan Finder Tool: A great starting point is the Medicare Plan Finder on Medicare.gov. This online tool allows you to enter your ZIP code and list of prescriptions and then shows you available Medicare Advantage and Part D drug plans in your area, complete with estimated costs. It lets you compare premiums, copays, drug coverage, star ratings, and more. Using Plan Finder can help you narrow down options based on total annual cost and coverage for your medications. You can also call 1-800-MEDICARE for help with comparisons. Take advantage of these resources – they’re there to make your research easier!

✔️ Check Provider Networks and Preferred Doctors: If keeping your current doctors (or accessing specific hospitals) is important to you, ensure they accept the coverage you choose. With Original Medicare, this is easy – ask if they accept Medicare (most do). With Medicare Advantage, you’ll want to check the plan’s provider directory to see if your primary care doctor and specialists are in-network. Also check which hospitals are included, especially if you have a preferred hospital. If a favorite doctor isn’t in an Advantage plan’s network, that could be a deal-breaker for that plan. On the flip side, if you don’t have strong preferences or your providers are in-network, an Advantage plan could work well. Always double-check each year, because networks can change.

✔️ Review Prescription Drug Coverage: Medications can be a big factor in costs. List out your prescriptions (name, dosage, how often you take them) and compare how they’d be covered under different plans. If you go with Original Medicare, you’ll compare Part D standalone plans – look at premiums, the formulary (does the plan cover your specific drugs?), and what tier/copay each drug is, as well as which pharmacies you can use. The Medicare Plan Finder makes this easy by calculating your yearly drug costs on each plan. If you’re considering a Medicare Advantage plan, make sure it includes Part D (most do, but a few types don’t), and check its drug coverage details too. Plans can differ widely – one plan might cover your drug with a $5 copay, another might charge $20 or require prior authorization. Pro tip: If you take expensive medications, also look at whether the plan has a deductible for drugs or uses a preferred pharmacy that could save you money. And remember, don’t delay enrolling in drug coverage when you’re first eligible – going 63+ days without creditable drug coverage could lead to a permanent Part D late enrollment penalty added to your premium.

✔️ Consider Your Lifestyle and Travel Needs: Your lifestyle can influence the best coverage. Do you split time between two states or travel frequently around the country? Original Medicare with a Medigap might be more convenient since coverage travels with you nationwide – no worrying about networks. Are you a homebody who stays mostly in one area and is happy with the local healthcare system? A Medicare Advantage plan centered around your local network could serve you well (and you can always use any plan for emergency care when traveling). If you plan to travel abroad a lot, note that Medicare generally doesn’t cover international care – but some Medigap plans do offer limited foreign emergency coverage, and a few Advantage plans might offer travel coverage as an extra benefit. Also, consider lifestyle perks: If an Advantage plan’s extras (like dental coverage or a fitness program) align with your needs – e.g., you haven’t had dental insurance and really want that – it might tilt the scales for you. On the other hand, if you already have coverage or don’t mind paying separately for dental/vision, that Advantage perk might not be as valuable.

✔️ Evaluate Your Health Needs and Budget: Think about how often you go to the doctor or need medical services, and your ability to handle out-of-pocket costs. If you have chronic conditions or see many specialists, an Advantage plan with copays might mean you’ll hit the out-of-pocket max each year – factor that in. With Original Medicare + Medigap, your costs would be mostly in the premiums, but very little per visit. If you’re relatively healthy and mostly use preventive services, you might prefer lower premiums and don’t mind paying copays occasionally – Advantage could save you money in that scenario. Also consider income: If Medigap premiums would strain your budget, an Advantage plan could be a more affordable way to get coverage (just be sure you’re comfortable with the cost-sharing when you do need care). It’s a balance between predictable higher premiums vs. pay-as-you-go costs. Do some math on annual cost under each scenario (premiums + expected out-of-pocket). Also, check if you qualify for programs like Medicaid or a Medicare Savings Program that can help with costs – that might influence your decision (e.g. Medicaid might cover Medicare cost-sharing if you’re low-income, which can pair with either Original or certain Advantage plans).

✔️ Read Reviews & Plan Ratings:Medicare gives each Advantage and Part D plan a Star Rating (1 to 5 stars) based on quality and customer satisfaction. A plan with 4 or 5 stars is considered high quality. While ratings aren’t everything, they can indicate how well the plan serves its members (things like customer service, ease of getting care, managing chronic conditions, etc.). Also, consider talking to friends or neighbors who have Medicare plans to hear their experiences, or reading reviews online (keeping in mind those are anecdotal). Your state’s State Health Insurance Assistance Program (SHIP) offers free counseling and can help explain options specific to your situation, which is a resource worth using if you’re unsure.

✔️ Annual Check-ups (For Your Plan!):Just as you get regular health check-ups, give your Medicare coverage an annual check-up. Medicare’s Annual Open Enrollment (Oct 15 – Dec 7) each year is your opportunity to change plans for any reason. Plans send out ANOC (Annual Notice of Change) letters explaining any changes for the coming year. Take a look – are your premiums going up? Are they dropping a favorite doctor or changing drug coverage? If you’re happy, you can do nothing and your plan continues. But if not, that’s the time to switch. Don’t be afraid to shop around each year. Insurance companies introduce new plans, and competing plans might offer better value or benefits. As one Medicare expert noted, comparing your options annually can save you money and ensure you’re getting the best coverage for your needs. Medicare Plan Finder is there for you every fall to compare anew.

Lastly, trust yourself and don’t get overwhelmed by sales pitches. If you get inundated by flyers or phone calls about Medicare plans (it happens!), know that you have the power of information now. Stick to reputable sources: Medicare.gov, official plan materials, and counselors who don’t have a sales stake.

Wrapping Up – You’ve Got This!

Choosing Medicare coverage is a big decision, but it doesn’t have to be intimidating. It’s about finding the right balance for your health needs, preferences, and budget. Whether that ends up being Original Medicare with a trusty Medigap and Part D plan, or a convenient Medicare Advantage plan packed with extras, the goal is to ensure you can access the care you need without unpleasant surprises.

Take your time to compare, use the tools and tips we discussed, and feel free to ask for help from Medicare or SHIP counselors if you need it. Once you’ve made your choice, you can rest easier knowing your healthcare is covered – and you can get back to enjoying life (and your well-earned retirement!). After all, Medicare is there to keep you healthy and protect you when you’re not, so choosing the right coverage is really about peace of mind.

I hope this guide has made Medicare a bit clearer, like chatting with a friend who’s been through it. Remember: there’s no “perfect” plan, only the plan that’s perfect for you. Here’s to your health and happiness in this next chapter! 🎉

What Is Medicare Part B and What Does It Actually Cover?

The complete guide to Medicare’s medical insurance — every service it covers, exactly what it costs in 2026, how it works with group insurance and VA benefits, and the excess charges most people have never heard of until they get a surprise bill.

The Short Answer

Medicare Part B is medical insurance — it covers doctor visits, outpatient care, preventive services, durable medical equipment, and more. Unlike Part A, Part B is not premium-free for anyone: everyone pays a monthly premium (202.90in2026formostpeople),anannualdeductible(283), and 20% coinsurance on most covered services, with no yearly cap on that 20% under Original Medicare alone. Whether you need to enroll at 65, and whether delaying is safe, depends heavily on your employment status and your employer’s size — getting this wrong is one of the most consequential and permanent mistakes in all of Medicare.

Key Takeaways

Part B is never premium-free — everyone pays a monthly premium, and higher earners pay significantly more through IRMAA.
The 20% coinsurance under Original Medicare alone has no yearly cap — this is the single biggest financial risk in Medicare, and it’s the reason Medigap and Medicare Advantage exist.
Whether you can safely delay Part B without a penalty depends on your employer’s size: 20+ employees generally allows delay; fewer than 20 generally does not.
Missing your enrollment window triggers a permanent 10% penalty for every 12-month period you went without coverage.
Veterans can and generally should enroll in Part B even with VA benefits, since Medicare and VA coverage don’t coordinate — each only pays for care received within its own system.
“Excess charges” from non-participating providers can add up to 15% on top of what Medicare approves, and only some Medigap plans protect you from them.

What Part B Actually Covers

While Part A handles hospital room and board, Part B is the half of Original Medicare that covers medical care and most services delivered outside a hospital admission — doctor visits, outpatient procedures, and ongoing medical needs.

What’s covered

Doctor visits — primary care and specialists
Outpatient surgeries and procedures
Diagnostic lab work, X-rays, and MRIs
Emergency room visits
Ambulance services
Outpatient mental health care
Physical, occupational, and speech therapy
Chemotherapy and radiation received in an outpatient clinic
Durable Medical Equipment (DME) — wheelchairs, oxygen equipment, blood sugar monitors, walkers, and similar equipment
Ambulatory surgical center services

Preventive services: the part Medicare gets genuinely right

Most preventive services are covered at 100%, with no deductible and no copay, as long as your provider accepts Medicare assignment. This includes:

Your one-time “Welcome to Medicare” wellness visit, available within your first 12 months on Part B
Annual wellness visits after that
Flu shots and most other recommended vaccines
Mammograms
Colonoscopies and other cancer screenings
Diabetes and cardiovascular screenings
Many other screenings recommended by the U.S. Preventive Services Task Force

Paul’s Honest Take: This is one of the most underused parts of Medicare, full stop. I’ve had clients who paid for a private physical every year out of habit and never realized their annual wellness visit through Medicare was completely free. If you haven’t used your Welcome to Medicare visit or your annual wellness visit, that’s real value sitting on the table.

What’s NOT covered

Routine dental care — cleanings, fillings, dentures, extractions
Routine vision exams and eyeglasses
Hearing aids (though diagnostic hearing tests ordered by a doctor may be covered)
Long-term custodial nursing home care — help with daily living activities, as opposed to short-term skilled or medical care
Routine prescription drugs you pick up at a retail pharmacy — that’s Part D’s job, not Part B’s
Cosmetic surgery, unless medically necessary (such as reconstruction after an accident or mastectomy)
Most care received outside the United States, with very limited exceptions
Routine foot care, such as nail trimming, in the absence of a qualifying medical condition
Acupuncture, except for a narrow, specific chronic low back pain benefit
Concierge medicine fees and membership-style charges some practices add on top of standard care
Long-term care insurance-style services, including most home-based personal care that isn’t tied to a skilled medical need

Paul’s Honest Take: The dental and vision exclusions are the ones that surprise people most, especially since they’re such routine parts of healthcare for most adults. This is exactly why so many Medicare Advantage plans build dental, vision, and hearing benefits into their coverage — Original Medicare was simply never designed to include them, and that gap doesn’t go away on its own.

What Part B Costs in 2026

Part B has three separate cost components, and understanding all three matters:

Cost Component	2026 Amount
Standard monthly premium	$202.90
Annual deductible	$283
Coinsurance on most covered services	20%

The premium is deducted automatically from your Social Security check if you’re already collecting benefits. If you’re not yet collecting Social Security, you’ll receive a bill, typically every three months.

The deductible works differently than Part A’s — it’s a straightforward annual figure. You pay the first $283 of Medicare-approved outpatient costs each calendar year, and then Medicare’s cost-sharing kicks in.

The coinsurance is where the real risk lives. After your deductible is met, Medicare pays 80% of the Medicare-approved amount for most covered services, and you’re responsible for the remaining 20%. There is no yearly cap on this 20% under Original Medicare alone. If you have a $100,000 course of cancer treatment, your 20% share is $20,000 — unless you have a Medigap policy or Medicare Advantage plan absorbing that cost.

Paul’s Honest Take: I put this in bold because it’s genuinely the single most important number in this entire guide. That uncapped 20% is the whole reason Medigap and Medicare Advantage exist as products in the first place. Original Medicare by itself was never designed to protect you from a truly expensive year — it was designed to cover 80% of it and leave the rest to you.

IRMAA: What Higher Earners Actually Pay

If your income is above certain thresholds, you’ll pay more for Part B through the Income-Related Monthly Adjustment Amount (IRMAA) — based on your tax return from two years prior. For 2026, that means your 2024 income determines your premium tier.

2024 Income (Individual)	2024 Income (Married, Joint)	Total Part B / Month
$109,000 or less	$218,000 or less	$202.90
$109,001 – $137,000	$218,001 – $274,000	$284.10
$137,001 – $171,000	$274,001 – $342,000	$405.80
$171,001 – $205,000	$342,001 – $410,000	$527.50
$205,001 – $499,999	$410,001 – $749,999	$649.20
$500,000 and above	$750,000 and above	$689.90

At the top tier, you’re paying more than three times the standard premium. If your income has recently dropped — retirement, the loss of a spouse, or certain other life-changing events — you can appeal your IRMAA determination using Form SSA-44.

Do You Have to Enroll? And What Happens If You Don’t?

Technically, Part B is optional — Medicare won’t force you into it. But opting out without a valid alternative is genuinely risky, because of how the penalty structure works.

If you don’t sign up during your Initial Enrollment Period (the 7-month window around your 65th birthday) and you don’t have qualifying employer coverage, you’ll face a permanent 10% penalty added to your premium for every full 12-month period you went without Part B. That penalty doesn’t expire — you pay it for as long as you have Part B, which for most people means for the rest of your life.

Example: If you delayed enrollment by 24 full months without a valid exception, you’d pay an extra 20% on top of the standard $202.90 premium in 2026 — roughly $40.58 more, every month, permanently.

How Part B Works with Group Insurance

Just like Part A, whether you can safely delay Part B without penalty comes down to one specific number: how many employees your company has.

Companies with 20 or more employees: If you or your spouse are actively working and covered by a genuine group health plan, your workplace insurance is primary, and you can legally delay Part B without any penalty. When that employment or coverage eventually ends, you get an 8-month Special Enrollment Period to enroll in Part B penalty-free.

Companies with fewer than 20 employees: Medicare automatically becomes your primary insurer at 65, regardless of your employment status. You need to enroll in Part B right on schedule. If you don’t, your small employer’s plan can legally refuse to pay claims that Medicare should have covered first — potentially leaving you responsible for the full cost.

Paul’s Honest Take: I say this in nearly every guide I write, because it’s genuinely one of the costliest misunderstandings I encounter: “I have good coverage at work” and “I’m protected from Medicare’s enrollment deadlines” are two completely different statements, and whether the second one is true depends entirely on your employer’s size — not how generous the coverage feels. Confirm the actual employee count before you decide to delay anything.

Retiree Coverage Is Not the Same as Active Employer Coverage

This is a distinction that catches a genuinely large number of people off guard: the “20 or more employees” exception only applies to active employment. If you retire and your former employer offers you retiree health benefits — sometimes a genuinely good, comprehensive plan — that coverage does not create a Special Enrollment Period the way active group coverage does, and it does not exempt you from enrolling in Part B on time.

Paul’s Honest Take: I’ve seen this mistake more than once, and it’s an especially painful one because it happens to people who did everything right during their working years. Someone retires with a strong retiree health plan from a large employer, assumes it works the same way their active coverage did, and delays Part B — only to find out later that retiree coverage was never a valid reason to delay in the first place. The moment you stop actively working, that clock starts, regardless of how good your retiree plan looks on paper. If you’re retiring and keeping employer retiree benefits, treat enrolling in Part B as something to handle right on schedule, not something retiree coverage lets you postpone.

Why You Need Both Part A and Part B for Medigap or Medicare Advantage

Here’s a foundational requirement worth understanding clearly, since it shapes every other coverage decision in Medicare: you must be enrolled in both Part A and Part B before you can buy a Medigap policy or enroll in a Medicare Advantage plan. Neither product exists as a standalone substitute for Original Medicare — both are built specifically to work alongside it.

Medigap fills the cost-sharing gaps left by Original Medicare (Parts A and B) — it has nothing to fill in if you’re not enrolled in both parts to begin with.
Medicare Advantage legally must provide at least the same coverage as Parts A and B combined, which is only possible because you’re required to be enrolled in both before a Medicare Advantage carrier can enroll you.

Paul’s Honest Take: This surprises people who assume they can somehow “skip” Part B and go straight into a Medicare Advantage plan to avoid the extra premium. It doesn’t work that way — Part B enrollment, and its premium, is a prerequisite either way, whether you end up on Original Medicare with Medigap or on a Medicare Advantage plan. There’s no path through Medicare that avoids the Part B premium once you’re actually using the system.

Does Medicare Work If You’re a Veteran?

Yes — and if you have VA health benefits, understanding how the two systems relate is genuinely important, because they work differently than most people assume.

Medicare and VA benefits do not coordinate. These are two entirely separate systems that each pay only for care received within their own network. Medicare doesn’t pay for care you receive at a VA facility, and VA benefits don’t pay for care you receive from a non-VA doctor or hospital. You, the veteran, choose which system to use each time you seek care.

Here’s the critical point: having VA benefits does not exempt you from Medicare’s enrollment deadlines. VA coverage is not considered a qualifying reason to delay Part B without penalty. If you don’t enroll in Part B during your Initial Enrollment Period and you’re relying solely on VA benefits, you can still trigger the permanent late enrollment penalty.

Why the VA itself recommends enrolling in Medicare anyway:

It gives you access to civilian doctors and hospitals outside the VA system
VA healthcare funding depends on annual Congressional appropriations, which isn’t guaranteed to remain stable
If VA authorizes only part of your needed care at a non-VA facility, Medicare can help cover the rest
Having both gives you meaningfully more flexibility and security than relying on either system alone

Paul’s Honest Take: This is one of the most common misconceptions I run into with veterans specifically, and it’s an expensive one to get wrong. Good VA coverage feels like it should be enough, and it might genuinely handle most of your care — but it doesn’t protect you from the Part B enrollment clock the way employer coverage from a large company can. The VA itself actively encourages enrolling in Medicare Parts A and B for exactly this reason. If you have VA benefits and are approaching 65, this is worth a direct conversation before you assume you’re covered.

Veterans who enroll in Part B can also purchase a Medigap policy, which can be particularly valuable if you use non-VA providers regularly — though if you primarily rely on VA facilities for most of your care, the value of an added Medigap policy may be more limited, and worth weighing carefully.

How Long Does It Actually Take to Get Part B Approved?

This is one of the most practical, and most overlooked, pieces of planning — especially if you’re leaving a job after 65 and coordinating your Part B start date around the end of your employer coverage. Applying isn’t instant, and the timeline depends heavily on which enrollment window you’re using.

Enrollment Situation	Typical Processing Time	When Coverage Actually Starts
Initial Enrollment Period (around 65)	2–4 weeks, sometimes up to 6	1st of your birthday month (if applied in the 3 months before) or 1st of the month after you apply (if applied during or after your birthday month)
Special Enrollment Period (leaving employer coverage)	4–8 weeks, sometimes longer	1st of the month after your application is submitted
General Enrollment Period (Jan 1–Mar 31, missed window)	4–6 weeks	1st of the month after you apply

Why the Special Enrollment Period takes longer: applying after leaving employer coverage requires two forms, not one — Form CMS-40B (the actual Part B application) and Form CMS-L564 (Request for Employment Information), which your employer needs to complete to verify you had qualifying coverage. Social Security has to manually review both, which is exactly why this route consistently takes longer than a standard Initial Enrollment Period application.

Paul’s Honest Take: This timeline question comes up constantly with clients who are retiring or leaving a job after 65, and it deserves real attention — not just because of the penalty risk we’ve already covered, but because a slow approval can leave you with an actual gap in coverage if you time it too tightly. My standard advice: start this process at least 2 to 3 months before you need Part B to actually begin, not the week your employer coverage ends. If your former employer is slow to complete their portion of Form CMS-L564, that alone can hold up the entire application — so it’s worth following up with your HR or benefits department directly rather than assuming it’s been submitted.

Practical tips to avoid delays

Apply online through SSA.gov whenever possible. It’s consistently the fastest method — mailed or faxed forms are more prone to getting lost or delayed.
If you’re on a Special Enrollment Period, submit Form CMS-L564 alongside Form CMS-40B, not separately. They need to arrive together, and one incomplete form can stall the whole application.
Expect a short intake lag even with online applications. It can take several business days for an online submission to actually appear on a local Social Security agent’s screen — don’t panic if you call shortly after applying and they say they don’t see it yet.
Once approved, you don’t have to wait for your physical card. Your Medicare Beneficiary Identifier typically appears in your online Social Security or Medicare.gov account within a day or two of approval, and you can print a temporary card from there — the physical card generally arrives by mail within about 30 days.

Excess Charges: The Cost Almost Nobody Knows to Ask About

Here’s a detail that surprises even people who’ve been on Medicare for years: not every doctor who accepts Medicare agrees to accept Medicare’s approved amount as full payment.

Providers fall into three categories:

Participating providers accept Medicare assignment, meaning they agree to accept the Medicare-approved amount as payment in full. This covers the vast majority of providers — roughly 98% of doctors nationally.
Non-participating providers still accept Medicare patients but haven’t agreed to accept the standard rate. They can charge an excess charge of up to 15% above the Medicare-approved amount.
Opted-out providers have left the Medicare system entirely and can charge whatever they want under a private contract — Medicare pays nothing at all for care from these providers, except in emergencies.

How excess charges actually work: if the Medicare-approved amount for a service is $300 and you see a non-participating provider, they can legally charge up to an additional $45 (15%) on top, for a total bill of $345 — and that excess amount doesn’t count toward your Part B deductible.

Eight states currently prohibit or limit excess charges entirely: Connecticut, Massachusetts, Minnesota, New York, Ohio, Pennsylvania, Rhode Island, and Vermont. If you live in one of these states, you’re generally shielded from excess charges from providers within your state — though you could still face them if you receive care from a non-participating provider elsewhere.

Paul’s Honest Take: This is exactly why Medigap Plan G matters so much for people who want maximum flexibility. Plan G covers excess charges in full — Plan N does not. If you’re the kind of person who wants the freedom to see any doctor without worrying about billing surprises, that distinction is worth understanding clearly before you pick between the two. And regardless of which plan you choose, it’s always worth asking a new provider directly whether they accept Medicare assignment before your first appointment.

The HSA Rule: Part B Closes the Door Too

If you’re hoping to keep contributing to a Health Savings Account, know this clearly: enrolling in Part B — or any part of Medicare — ends your ability to make new HSA contributions. This isn’t unique to Part B; it applies the moment you enroll in Medicare in any form, including premium-free Part A.

If keeping your HSA active matters to you, the only way to legally delay both Part A and Part B is through qualifying employer coverage — which, as covered above, generally requires an employer with 20 or more employees. And because Part A enrollment can be backdated up to 6 months once you do enroll, it’s smart to stop HSA contributions 6 months before you plan to sign up for Medicare or file for Social Security, whichever comes first.

Frequently Asked Questions

Is there a cap on what I’ll pay for Part B services in a year? Not under Original Medicare alone — the 20% coinsurance has no yearly limit. A Medigap policy or Medicare Advantage plan is what actually caps your exposure.

What happens if I don’t sign up for Part B on time? You’ll generally face a permanent 10% penalty on your premium for every 12-month period you went without coverage, unless you qualify for a Special Enrollment Period through active employer coverage.

Do I need Part B if I have good coverage through a small employer? Almost certainly yes. If your employer has fewer than 20 employees, Medicare becomes your primary insurer at 65 regardless of your job coverage, and not enrolling can leave you exposed to unpaid claims and a lifelong penalty.

Do veterans need Medicare Part B if they have VA benefits? Generally, yes. Medicare and VA benefits don’t coordinate — each only pays for care within its own system — and VA coverage doesn’t exempt you from Medicare’s enrollment deadlines or penalties.

What is a Part B excess charge? An additional charge, up to 15% above the Medicare-approved amount, that a non-participating provider can legally bill you. It doesn’t count toward your deductible, and only Medigap Plan G (among current plans) covers it in full.

Can I keep contributing to my HSA if I enroll in Part B? No. Enrolling in any part of Medicare, including Part B, ends your HSA contribution eligibility going forward.

How long does it take to get approved for Part B? It depends on the enrollment window. Initial Enrollment Period applications typically process in 2–4 weeks. Special Enrollment Period applications, used when leaving employer coverage, generally take 4–8 weeks since Social Security must manually verify your prior coverage using Form CMS-L564. Start the process at least 2–3 months before you need coverage to begin, especially when coordinating around a job ending.

The Bottom Line

Part B is the half of Medicare that covers your everyday medical care — and it’s also where the real financial exposure of Original Medicare lives, thanks to that uncapped 20% coinsurance. Whether you should enroll at 65, whether you can safely delay, and how much of that exposure you’re carrying all depend on details specific to your situation: your employer’s size, your income, your VA status, and which doctors you actually see.
