Medicare SELECT Plans: What You Need to Know

Medicare SELECT is a version of standardized Medigap (Medicare Supplement) insurance that requires you to use a specific network of hospitals and sometimes doctors for non-emergency services. It offers the same lettered-plan benefits as a standard Medigap policy when you stay in-network, but typically at a lower monthly premium. For most people, it’s the right call if you live near your preferred hospitals, rarely travel for care, and want to keep monthly costs down.

Here’s the core trade-off at a glance:

  • Lower premiums in exchange for using a defined provider network for non-emergency care
  • Same benefits as the corresponding lettered Medigap plan (Plan G SELECT = standard Plan G benefits, in-network)
  • Emergency care is always covered regardless of network, under Original Medicare rules
  • No coverage from the SELECT policy for non-emergency care at out-of-network facilities

Pro Tip: Most new SELECT enrollees have a 12-month trial window to switch to a standard Medigap plan without medical underwriting. If you try SELECT and find the network too limiting, that safety valve protects you.

How does Medicare SELECT work day to day?

The operational difference between SELECT and standard Medigap comes down to one word: network. For non-emergency hospital stays and, depending on the policy, specialist visits, you must use providers in the plan’s approved network to receive full benefits.

In-network care works exactly like standard Medigap. Original Medicare pays its share, and your SELECT policy covers the gaps it’s designed to cover under that letter plan.

Out-of-network, non-emergency care is a different story. Original Medicare still pays its share of approved charges, but the SELECT policy pays nothing. That means you’re on the hook for whatever Original Medicare doesn’t cover, which can be substantial for a hospital stay.

Emergency and urgent care are the exception. If you’re in a genuine medical emergency, Original Medicare covers you regardless of where you are or which hospital treats you. Your SELECT policy follows suit. Traveling out of state and needing emergency care? You’re covered. Scheduling elective knee surgery at an out-of-state hospital because you prefer that surgeon? That’s where SELECT leaves you exposed.

A few other operational rules worth knowing:

  • Some SELECT policies require a referral from a primary care physician to see a specialist, which standard Medigap plans do not require
  • Network size varies significantly by insurer and region; a SELECT plan in a major metro may have dozens of in-network hospitals, while a rural plan might have only a handful
  • Provider directories can change, so a hospital that’s in-network today may not be next year

Pro Tip: Always ask the insurer for a current provider directory for your specific ZIP code before enrolling. A plan that lists 40 hospitals statewide may have only two within a reasonable drive of your home.

Does SELECT give you the same coverage as standard Medigap?

Yes, with one critical qualifier: the benefits are identical when you use in-network providers. Medicare SELECT plans follow the same standardized letter structure (A through N) as regular Medigap plans, so a SELECT Plan G covers exactly what a standard Plan G covers, including Part A coinsurance, Part B coinsurance, skilled nursing facility coinsurance, and the Part A deductible. The insurer cannot strip out benefits just because it’s a SELECT version.

What changes is where those benefits apply. Here’s how the two plan types compare across the dimensions that matter most:

Dimension Medicare SELECT Standard Medigap
Provider access In-network hospitals (and sometimes doctors) required for non-emergency care Any provider that accepts Medicare, nationwide
Monthly premium Generally lower Generally higher
Benefit equivalence Identical to the same letter plan, in-network Identical to the same letter plan, anywhere
Emergency/out-of-area care Covered under Original Medicare rules Covered under Original Medicare rules
Out-of-network non-emergency SELECT policy pays nothing; Original Medicare pays its share Covered per plan benefits, no network limit

One thing SELECT is not: it is not Medicare Advantage. Advantage plans replace Original Medicare entirely. SELECT supplements it. You cannot hold a SELECT plan and a Medicare Advantage plan simultaneously, the same rule that applies to all Medigap policies.

When you’re reading that table to make a decision, focus on the bottom two rows. The premium difference only matters if the network actually covers the providers you use. If it doesn’t, the savings evaporate fast.

Why are Medicare SELECT premiums lower, and what drives your total cost?

Premiums are lower because insurers limit where they must pay full benefits. By restricting coverage to a defined network, the insurer controls its risk exposure. Fewer covered claims means lower pricing passed on to you as a lower monthly premium.

But premium is only one piece of the cost picture. Your real annual cost includes the monthly Medigap premium, your Original Medicare Part B premium, and the potential out-of-pocket exposure if you receive non-emergency care outside the network. That last number is the one most people underestimate.

Other factors that affect what you pay:

  • Plan letter: A SELECT Plan G will cost more than a SELECT Plan N because Plan G covers more
  • Age-rating method: Community-rated, issue-age-rated, and attained-age-rated policies price differently over time
  • Location: Premiums vary by state and even by county
  • Insurer pricing practices: Two insurers can offer the same SELECT Plan G in the same ZIP code at very different prices
Cost driver What to ask your insurer or agent
Network size How many in-network hospitals are near my home?
Out-of-network exposure What would I owe for a 3-day hospital stay at an out-of-network facility?
Premium rating method Is this community-rated, issue-age-rated, or attained-age-rated?
Annual premium increases What has the average rate increase been over the past five years?
Part B premium Am I accounting for the standard Part B premium on top of this?

Pro Tip: Run a simple annual cost estimate: (monthly SELECT premium × 12) + (Part B premium × 12) + a realistic out-of-network risk buffer. Compare that total to the same calculation for a standard Medigap plan. The gap is often smaller than the monthly premium difference suggests.

Pros, cons, and who SELECT actually fits

SELECT isn’t for everyone. Here’s the honest breakdown.

Pros:

  • Lower monthly premiums than a comparable standard Medigap plan
  • Identical benefits to the same letter plan when you stay in-network
  • Predictable costs for people who use a stable set of local hospitals
  • The trial window lets you test it without permanent commitment

Cons:

  • No SELECT policy benefits for non-emergency out-of-network care; you absorb what Original Medicare doesn’t pay
  • Some policies require specialist referrals, adding an administrative step standard Medigap doesn’t have
  • Network availability is limited in some states and rural areas
  • Switching to a standard Medigap plan after the 12-month window may require medical underwriting

Who it fits best: People on fixed incomes who use a consistent set of local hospitals and rarely travel for medical care. If your cardiologist, primary care doctor, and preferred hospital are all in-network, SELECT can save you real money every month with no practical downside.

Who should think twice: Frequent travelers, snowbirds, anyone with multiple specialists across different health systems, and people who might relocate in the next few years.

Ask yourself these questions before enrolling:

  • Do I travel more than a few weeks per year and might need non-emergency care away from home?
  • Are all my current specialists and preferred hospitals in the plan’s network?
  • Could I absorb a large unexpected bill if I needed out-of-network care?
  • Am I likely to move in the next two to three years?

Pro Tip: If you’re unsure, enroll in SELECT and use the 12-month trial window deliberately. Track every provider interaction. If you hit a network friction point, switch to standard Medigap before the window closes.

Where is Medicare SELECT available, and how do state rules affect it?

Not every insurer offers SELECT, and not every state has robust SELECT options. Availability depends on whether an insurer has chosen to file a SELECT product in your state and whether it has built a provider network there. In some states, SELECT plans are common. In others, you may find only one or two insurers offering them, or none at all in your county.

State insurance departments oversee Medigap plan filings, including SELECT. They can tell you which companies are licensed to sell SELECT in your state and what consumer protections apply. The New York Department of Financial Services, for example, publishes specific guidance on SELECT rules for New York residents. Most state insurance departments maintain similar resources.

What to check before you assume a plan is available:

  • Your state insurance department’s website for a list of licensed SELECT insurers
  • The insurer’s provider directory filtered to your ZIP code or county
  • Whether the network includes your current primary care physician and any specialists you see regularly
  • Whether the network extends to any hospitals you might use while traveling within your state

If you move out of the SELECT plan’s coverage area, you typically qualify to switch to a standardized Medigap plan, and some moves trigger guaranteed-issue rights that protect you from underwriting. That’s a meaningful consumer protection, but it requires you to act promptly when the move happens.

Pro Tip: Don’t rely on the insurer’s marketing materials to confirm network coverage. Call the insurer directly, ask for the provider directory for your specific ZIP code, and verify that your current providers are listed before you sign anything.

Who can enroll in Medicare SELECT, and when?

The eligibility rules for SELECT mirror those for all Medigap policies. You must have Original Medicare Parts A and B, and you cannot hold a Medigap plan and a Medicare Advantage plan at the same time.

Enrollment steps:

  1. Confirm you have Original Medicare Parts A and B active
  2. Identify your Medigap Open Enrollment Period: it begins the month you turn 65 and are enrolled in Part B, and lasts six months
  3. During that window, you have guaranteed-issue rights, meaning no insurer can deny you or charge more based on health history
  4. Outside that window, most states allow medical underwriting, which can result in higher premiums or denial
  5. Enroll in a SELECT plan through a licensed insurer in your state
  6. Within the first 12 months, you retain the right to switch to a standard Medigap plan without underwriting

Key documents and questions to have ready:

  • Your Medicare card (showing Parts A and B effective dates)
  • A list of your current providers and hospitals
  • The insurer’s provider directory for your ZIP code
  • Written confirmation of the referral rules, if any, for specialist visits
  • The insurer’s rate increase history for the past three to five years

People under 65 on Medicare due to disability face a different landscape. Federal law does not require insurers to sell Medigap to people under 65, though some states do mandate it. Check your state’s Medigap eligibility rules before assuming you can enroll.

For a broader look at enrollment timing and how to avoid late penalties, the Medicare enrollment guidance at Paulbinsurance walks through the full timeline step by step.

How do you decide between SELECT and standard Medigap?

The decision comes down to three variables: your provider relationships, your travel patterns, and your budget tolerance for unexpected bills. Here’s a practical framework.

Decision checklist:

  • Map your current providers. Are your primary care doctor, all active specialists, and your preferred hospital in the SELECT plan’s network?
  • Estimate your travel exposure. Do you spend significant time in another state or region where you might need non-emergency care?
  • Calculate total annual cost for both options (see the cost section above). Is the premium difference meaningful enough to justify the network constraint?
  • Assess your ability to absorb a surprise bill. If an out-of-network non-emergency hospital stay would create financial hardship, standard Medigap is the safer choice.

Questions to ask the insurer or your agent:

  1. Which specific hospitals and physician groups are in-network for my ZIP code?
  2. Does this plan require referrals to see specialists, and is that requirement in writing?
  3. Can you show me an example of what I would owe for a three-day in-network hospital stay versus an out-of-network one?
  4. What is the plan’s rate increase history over the past five years?
  5. If I switch to a standard Medigap plan within 12 months, which plans am I guaranteed access to?

Red flags to watch for:

  • A provider directory that’s hard to access or hasn’t been updated recently
  • Vague or inconsistent answers about referral requirements across different sales channels
  • A network with fewer than three or four in-network hospitals in your immediate area
  • Aggressive underwriting language in the application that suggests the insurer expects to deny applicants

Pro Tip: Ask the insurer for a sample explanation of benefits showing a denied out-of-network non-emergency claim. Seeing the actual dollar exposure in writing is more persuasive than any premium comparison spreadsheet.

What an experienced Medicare agent looks for in a SELECT fit

Medicare SELECT tends to work best for fixed-income retirees who reliably use a small set of local hospitals and providers. That’s not a generalization; it’s a pattern that shows up consistently when you look at who actually benefits from the premium savings without hitting network friction.

The clients who run into trouble with SELECT are almost always in one of these situations:

  • They travel frequently and need non-emergency care while away from home
  • They have multiple specialists who practice at different hospital systems, some of which are out-of-network
  • They have a chronic condition that requires care at a specialized center not in the SELECT network
  • They moved after enrolling and didn’t act quickly enough to trigger their guaranteed-issue rights

A network fit check, done properly, takes about 15 minutes. You pull the insurer’s provider directory, cross-reference it against the client’s current provider list, and then run one or two sample claim scenarios: an elective hospital stay in-network, and the same stay out-of-network. The dollar difference between those two scenarios tells you more than any premium comparison.

Pro Tip: The trial window exists because network fit is hard to predict from a directory alone. If a client is genuinely uncertain, enrolling in SELECT and tracking real-world network friction is a legitimate strategy, as long as they know the window closes.

For clients still deciding between SELECT, standard Medigap, and Medicare Advantage, the Advantage vs. supplement comparison at Paulbinsurance lays out the structural differences clearly.

Key Takeaways

Medicare SELECT offers the same lettered Medigap benefits as a standard plan but restricts full coverage to in-network providers for non-emergency care, making it a strong fit for cost-conscious beneficiaries with stable, local provider relationships.

Point Details
Same benefits, network rules A SELECT Plan G covers the same benefits as standard Plan G, but only when you use in-network providers.
Lower premiums, real exposure risk Premiums are lower because the insurer limits where it pays; out-of-network non-emergency care leaves you covering what Original Medicare doesn’t pay.
12-month trial window New enrollees can switch to a standard Medigap plan within 12 months without medical underwriting.
State and insurer availability varies Not all states or insurers offer SELECT; always verify network coverage for your specific ZIP code before enrolling.

Why education-first advice matters when evaluating SELECT

Most people who call asking about Medicare SELECT have already seen the lower premium and want to know if there’s a catch. There is, but it’s not the same catch for everyone. That’s the part generic guides miss.

The conventional wisdom is that SELECT is “good for healthy people who don’t use much care.” That framing is backwards. The people who benefit most from SELECT aren’t the ones who use little care; they’re the ones who use care predictably, at a consistent set of local providers. A person with a serious chronic condition who sees the same cardiologist at the same in-network hospital every three months is often a better SELECT candidate than a healthy 66-year-old who travels six months a year.

The 12-month trial window is genuinely underused. Most agents mention it once and move on. It deserves more emphasis because it changes the decision calculus entirely. You don’t have to be certain SELECT is right for you before enrolling. You have to be willing to pay attention for 12 months and act if the network creates real friction.

One more thing worth saying plainly: the provider directory is a living document. A hospital that’s in-network when you enroll can leave the network mid-year. Ask the insurer what happens to your coverage if a key provider leaves the network, and get the answer in writing.

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.
