Medicare Beneficiaries: 2026 $2,950 High Deductible Plan G Explained

High-deductible Plan G carries a $2,950 annual deductible in 2026, set by the Centers for Medicare & Medicaid Services. Once you pay that amount in Medicare-covered costs, the plan pays exactly like standard Plan G, dollar for dollar. It generally appeals to new-to-Medicare beneficiaries who want a lower monthly premium and can handle the risk of a high-cost year.

TL;DR:

  • The $2,950 deductible for high-deductible Plan G in 2026 is increasing by $150 from 2024, and it resets every January 1, regardless of enrollment date.
  • Only those eligible for Medicare on or after January 1, 2020, can generally buy high-deductible Plan G, with availability varying widely by state and carrier.
  • The plan covers the same benefits as standard Plan G once the deductible is met, but not all healthcare expenses count toward the $2,950 threshold, such as foreign travel emergency benefits.
  • Premium costs are lower for high-deductible Plan G, making it suitable for healthy beneficiaries with sufficient savings to handle potential large out-of-pocket costs.
  • Comparing actual premiums and running cost scenarios based on personal health and expected expenses helps determine if high-deductible Plan G offers real savings in your ZIP code.

How Does High Deductible Plan G Work?

High-deductible Plan G doesn’t change what’s covered. It changes when coverage kicks in. You pay Medicare-approved costs out of pocket until you hit the deductible, and after that, the plan picks up the same benefits as standard Plan G, including Part A coinsurance, Part B coinsurance, and the first three pints of blood. Medicare confirms Plans F and G both offer this high-deductible option, and the policy pays only after you’ve paid Medicare-covered costs up to that deductible.

What actually counts toward the $2,950? Not every dollar you spend on health care applies.

  • The Part B deductible you pay each year
  • Part A and Part B coinsurance amounts for Medicare-covered services
  • Copayments tied to Medicare-approved charges

One wrinkle catches people off guard: the foreign travel emergency benefit, if your policy includes it, has its own separate deductible and coinsurance structure. It doesn’t count against your $2,950 plan deductible. Carrier documentation, including UnitedHealthcare’s plan description, consistently frames this as a calendar-year deductible, meaning it resets every January 1, not on your policy anniversary.

Who Qualifies for High Deductible Plan G?

Not everyone can buy this plan. Eligibility hinges on when you first became eligible for Medicare, and carriers apply the rule strictly.

  • You generally need to have become eligible for Medicare on or after January 1, 2020, to purchase high-deductible Plan G (this also applies to the discontinued Plan F).
  • “New to Medicare” typically means your Part A effective date, or in some cases your 65th birthday, falls on or after that 2020 cutoff.
  • Availability isn’t universal. Some carriers skip the high-deductible option entirely, and offerings shift by state, so a plan sold in Ohio might not exist in Nevada.
  • Enrollment timing matters too. Your strongest guaranteed-issue window is the six months after your Part B effective date, though rules vary by state.

Because availability is so ZIP-code dependent, checking with an agent before assuming this plan is even on your menu saves a lot of wasted research.

What Does High Deductible Plan G Cost in 2026?

The 2026 deductible is $2,950, up from $2,800 in 2024, and CMS recalculates it every year using the Consumer Price Index for Urban Consumers (CPI-U), following a formula written into Section 1882(p)(11)©(i) of the Social Security Act. That means the number you budget for this year won’t be the number you budget for in three years. Expect it to drift upward, not down.

Fast fact: The high-deductible Plan G threshold for 2026 sits at $2,950, a $150 jump from the 2024 figure of $2,800.

Premiums run lower on high-deductible Plan G than standard Plan G, because you’re absorbing more of the early-year risk and the insurer is carrying less of it. How much lower depends entirely on your carrier and ZIP code, but the trade-off is real: cheaper premium, bigger exposure if your health takes a turn.

Think through two rough scenarios:

  1. Low-use year. You visit the doctor a handful of times, get routine labs, maybe one urgent care visit. You might spend a few hundred dollars in Medicare-covered costs, never approaching the deductible, and pocket the premium savings all year.
  2. High-use year. A surgery, a hospital stay, or a new chronic diagnosis pushes you past $2,950 in covered costs relatively fast. From that point forward you’re covered like standard Plan G, but you’ve paid the full deductible plus your lower premium.

The only way to know which scenario is more likely for your budget is to get an actual ZIP-level premium quote and compare it side by side with standard Plan G pricing, as premiums vary by location and carrier.

Is High Deductible Plan G Worth It for You?

The math favors different people in different situations, and there’s no universal right answer here.

The case for it:

  • Lower monthly premiums free up cash flow, especially useful if you’re on a fixed income
  • Coverage matches standard Plan G exactly once you clear the deductible
  • Your maximum annual exposure is capped and known in advance. The deductible IS your worst-case number, which makes budgeting easier than plans with looser gaps

The case against it:

  • A single bad health year can hit you with the full $2,950 in out-of-pocket costs before benefits fully kick in
  • If you’re already managing several chronic conditions with predictable annual costs, you may hit the deductible every year anyway, erasing the premium advantage
  • Beneficiaries without much savings cushion can feel real strain absorbing that deductible in one lump sum or spread across a few months

Healthy beneficiaries with modest reserve savings tend to do well here. Someone managing diabetes, heart disease, or another condition with frequent specialist visits usually comes out ahead on standard Plan G instead.

Pro Tip: Ask your agent to run your last two years of actual medical bills against the $2,950 threshold. If you cleared it both years, high-deductible Plan G probably isn’t saving you anything.

How Do You Decide Between High Deductible and Standard Plan G?

Run through this before you call anyone:

  1. Tally your expected annual costs. Look at last year’s doctor visits, labs, and any planned procedures for 2026.
  2. Check your cash cushion. Could you pay $2,950 in a single year without disrupting your budget?
  3. Compare the premium gap. Get quotes for both standard and high-deductible Plan G in your ZIP code, not a national average.
  4. Factor in prescriptions and planned surgery. A knee replacement already on the calendar changes the calculation instantly.

When you talk to an agent, ask these directly:

  • Exactly which of my costs count toward the deductible, and which don’t?
  • What’s the real premium difference for my ZIP code, in writing?
  • Does this carrier even offer the high-deductible option where I live?
  • Does my foreign travel emergency benefit have a separate deductible?

Request a written comparison, then simulate both a “good year” and a “bad year” cost total for each plan. That simple exercise usually makes the decision obvious.

How Do You File Claims Under High Deductible Plan G?

Claims processing works almost identically to standard Plan G, with one key difference: your carrier is tracking your deductible balance behind the scenes. Medicare processes your claim first and sends the details electronically to your Medigap insurer through the Medicare crossover system, so in most cases you don’t file paperwork yourself.

Before you hit the $2,950 threshold, your Explanation of Benefits will show Medicare’s payment and your responsibility for the remainder, since the plan hasn’t started paying yet. Keep every EOB. They’re your running tally of how close you are to the deductible, and disputes are much easier to resolve with paper in hand.

Once your cumulative Medicare-covered costs cross $2,950 for the calendar year, the plan begins paying its share automatically on subsequent claims. You typically don’t need to submit a separate reimbursement request. If a provider bills you directly instead of billing through the standard crossover process, contact your carrier’s member services line. They can walk you through submitting an itemized bill and a copy of your Medicare Summary Notice for manual processing.

Any confusion usually happens right at the deductible crossover point, when a claim spans both sides. Carriers handle this by splitting the claim, applying the remaining deductible balance first, then paying the plan’s portion on the rest. If your statement looks confusing that month, that split is almost always the reason.

How Does High Deductible Plan G Compare to Other High Deductible Supplement Options?

Plan G isn’t the only Medigap option sold with a high-deductible version. High-deductible Plan F exists too, but only for beneficiaries who became eligible for Medicare before January 1, 2020, since Plan F was phased out for newly eligible enrollees after that date.

The two plans share the same $2,950 deductible figure and the same underlying logic: lower premium, same rich coverage once you clear the threshold. The difference between them is what they cover before the deductible even becomes relevant. Standard Plan F covers the Part B deductible itself as one of its benefits; standard Plan G does not. In high-deductible form, that distinction mostly evaporates, because you’re paying out of pocket up to $2,950 regardless of which plan you hold. If you’re eligible for both, high-deductible Plan G tends to run at a similar or slightly lower premium in most markets, and it’s the only high-deductible option available to anyone who became Medicare-eligible in 2020 or later.

There’s no high-deductible version of Plan N or the other letter plans. Those plans build in different cost-sharing structures, like flat copays for office visits, instead of a large upfront deductible. If a large deductible feels too risky but you still want a lower premium than standard Plan G, Plan N is worth comparing, though it works on a completely different cost model and isn’t a direct substitute.

What’s the Yearly Timeline for Meeting the Deductible?

The $2,950 deductible resets every January 1, regardless of when your policy started. If you enrolled in March, your first partial year runs from your effective date through December 31, and the following January the full clock resets.

Most beneficiaries clear the deductible unevenly across the year. Someone with a January surgery might hit the full $2,950 by February and get eleven months of standard Plan G-level coverage afterward. Someone who stays healthy until a fall diagnosis might not cross the threshold until October, leaving little runway before the reset hits again on January 1.

This creates a real planning wrinkle for procedures you can schedule. A knee replacement planned for December instead of January means paying most of the deductible right before it resets days later, effectively doubling your exposure across the calendar boundary. Beneficiaries who know a major procedure is coming often ask their doctor about timing flexibility for exactly this reason.

High Deductible Plan G yearly timeline

Track your progress toward the deductible using your Medicare Summary Notices, which arrive quarterly, or check your claims history online at Medicare.gov. Your Medigap carrier also tracks this internally and can tell you your current balance if you call.

Does High Deductible Plan G Affect Your Part D Drug Coverage?

High-deductible Plan G has no relationship to your Part D prescription drug plan. They’re entirely separate policies with separate deductibles, and meeting one has zero effect on the other. Your $2,950 Medigap deductible only applies to Medicare Part A and Part B covered costs, medical services, hospital stays, and outpatient care. It never touches prescription costs.

Your Part D plan runs its own deductible, initial coverage phase, and catastrophic coverage phase, all independent of whatever Medigap plan you carry. A beneficiary on high-deductible Plan G shops for Part D exactly the same way as someone on standard Plan G, comparing formularies, pharmacy networks, and monthly premiums specific to their medications.

The one place these two policies interact is your total household budget, not the coverage mechanics. If you’re already stretching your monthly premium dollars thin between a high-deductible Medigap plan and a Part D plan with high drug costs, that combined math matters more than either policy in isolation. Run both numbers together, not separately, when deciding if the premium savings on high-deductible Plan G actually help your overall finances.

FAQ

Is Medicare High Deductible Plan G Worth It?

It’s worth it if you’re generally healthy, have savings to cover $2,950 in a bad year, and want lower monthly premiums than standard Plan G. It’s usually not worth it if you have chronic conditions with predictable annual costs that already exceed the deductible most years.

What Are the Disadvantages of High Deductible Plan G?

The biggest disadvantage is exposure to the full $2,950 deductible in any year with significant medical needs, which can strain a fixed income if it arrives unexpectedly. It also isn’t available to everyone. Only those who became eligible for Medicare on or after January 1, 2020, can typically purchase it.

Does UnitedHealthcare Offer High Deductible Plan G?

Yes, UnitedHealthcare offers a Medicare Supplement High Deductible Plan G product that pays the same benefits as standard Plan G once the calendar-year deductible is met. Availability and pricing still depend on your state and ZIP code, so confirming local availability matters before assuming it’s an option.

Which Medicare Plan G Option Is Best for New Enrollees?

There’s no single best option. It depends on your expected medical spending, your savings cushion, and how much premium difference exists in your ZIP code between standard and high-deductible versions. Paulbinsurance compares both side by side using real, current quotes so new enrollees can decide based on their own numbers rather than a generic recommendation.

What Counts Toward the High Deductible Plan G Deductible?

Medicare-covered costs count, including your Part B deductible, Part A and Part B coinsurance, and copayments tied to Medicare-approved charges. The foreign travel emergency benefit runs on a separate deductible and doesn’t count toward your $2,950 plan deductible.

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.

If you want help sorting out exactly how Part B applies to your specific circumstances — or want to understand how Medigap or Medicare Advantage could close that uncapped coinsurance gap — that’s exactly the conversation I have with clients every day, at no cost to you.
