Medicare Supplements in 2026: What’s Changed, What Hasn’t, and How to Choose Confidently

Medicare Supplement (Medigap) plans can help control out-of-pocket costs in 2026. Here’s what’s new this year, how plans compare, and how to pick the right fit.

If you’re on Original Medicare in 2026, predictability matters more than ever

Original Medicare (Parts A & B) is solid coverage — but it doesn’t include an out-of-pocket maximum, and cost-sharing can add up quickly. That’s where Medicare Supplement Insurance (Medigap) comes in: it helps pay some of the “gaps” that Original Medicare doesn’t cover.

In 2026, a few key costs increased, which makes a Medigap review (or first-time purchase) especially important:

  • Standard Medicare Part B premium: $202.90/month

  • Medicare Part B deductible: $283/year

  • Medicare Part A inpatient deductible: $1,736 per benefit period

Those numbers are a big reason many people choose Medigap — it can turn unpredictable bills into something much more manageable.

What is a Medicare Supplement (Medigap) plan?

A Medigap policy is private insurance that works only with Original Medicare (Part A and Part B). It helps cover out-of-pocket costs like:

  • Part A hospital coinsurance and deductible

  • Part B coinsurance (often the 20% you’d otherwise pay)

  • Copayments, coinsurance, and certain other gaps, depending on the plan letter

Medigap plans are standardized in most states (plans are labeled A–N), which means the benefits for a given plan letter are the same regardless of the company; the main difference is price and customer service.

Important: You generally can’t have Medigap and Medicare Advantage at the same time. Medigap supplements Original Medicare; Medicare Advantage is an alternative way to receive your Medicare benefits.

What’s new for Medigap in 2026?

1) Higher Medicare “baseline” costs

Because Medicare Part A and Part B costs increased for 2026, the value of having a supplement that reduces cost-sharing is more noticeable than ever. The 2026 Part A deductible, Part B premium, and Part B deductible are published by CMS.

2) High-deductible Medigap options updated for 2026

If you’re considering a high-deductible option (often chosen for lower premiums), the 2026 high-deductible amount for Plans F, G, and J is $2,950.

The most common Medigap choices (and who they fit best)

While there isn’t a single “best” plan for everyone, these tend to be the most talked-about options:

Plan G: Strong coverage, widely popular

Plan G is often considered the “go-to” comprehensive option for people newly eligible for Medicare, because it covers most gaps except the Part B deductible. (So you typically pay the Part B deductible first, then your plan coverage kicks in per the plan rules.)

Good fit if you want: fewer surprise bills and broad coverage.

Plan N: Lower premium, some cost-sharing

Plan N can offer lower premiums than Plan G, but you may pay certain copays (for example, some office visits and some ER visits that don’t result in admission) depending on the rules of the standardized plan.

Good fit if you want: lower premiums and you’re comfortable with some copays.

High-Deductible Plan G: Premium savings with a bigger “self-pay” threshold

High-deductible Plan G can be a smart strategy for people who want a lower monthly premium and are comfortable covering more costs upfront. For 2026, that deductible threshold is $2,950.

Good fit if you want: the structure of Plan G but at a lower premium, and you have room in your budget for higher upfront exposure.

Plan F: Only for those eligible before 2020

Plan F is still available only to people who were eligible for Medicare before January 1, 2020 (even if they enrolled later).

The #1 timing mistake people make in 2026: waiting too long

The best time to buy a Medigap plan is during your Medigap Open Enrollment Period:

  • It’s a one-time 6-month window that starts when you’re 65+ and enrolled in Part B.

  • During this period, companies generally can’t deny you coverage or charge more due to health conditions.

After that window, in many states, you may face medical underwriting (health questions), and acceptance/pricing can change.

Medigap doesn’t cover everything (and that’s normal)

A Medicare Supplement plan is designed to help with Original Medicare cost-sharing — but it typically does not include:

  • Prescription drug coverage (you’ll usually need a Part D plan)

  • Dental, vision, and hearing

  • Long-term care

So the “complete” setup for many people is often:
Original Medicare + Medigap + Part D (and optionally dental/vision coverage separately).

Quick 2026 checklist: choosing the right Medicare Supplement

If you’re comparing options this year, here are the questions I walk clients through:

  1. Do you want the most predictable costs possible? (Plan G-style thinking)

  2. Are you okay with some copays to reduce premiums? (Plan N-style thinking)

  3. Would you rather save monthly and self-fund more upfront? (High-deductible G)

  4. Are you still in your Medigap Open Enrollment window?

  5. Do you take prescriptions that makethe  Part D plan choice important?

  6. Do you travel often or want nationwide provider flexibility? (Often, a reason people prefer Original Medicare + Medigap over network-based alternatives.)

Want help comparing Medigap plans for 2026?

Choosing a Medicare Supplement can feel confusing — especially when premiums vary by company, even though the plan letter benefits are standardized. If you’d like help comparing options based on your doctors, budget, and preferred level of predictability, I’m happy to help.

Your Medicare Plan May Be Changing—Even If Your Health Hasn’t

You’re happy with your doctors. Your prescriptions haven’t changed. Your Medicare coverage worked well this year. So, is reviewing your plan really necessary? It’s a worthwhile step. Your healthcare needs may stay the same while your plan’s costs and coverage change. Taking time to review the details this fall can help you make a more informed decision about the year ahead. Medicare Open Enrollment runs October 15 through December 7 each year. Changes made during this period take effect January 1, as long as the plan receives your enrollment request by December 7. That means this fall’s enrollment decisions affect your coverage for 2027. Start With the Notice You Might Be Tempted to Skip If you have a Medicare Advantage or prescription drug plan, your plan sends an Annual Notice of Change, often called an ANOC, each fall. It explains changes to costs, coverage, and other plan details that begin

Medicare Open Enrollment 2027: 7 Things to Review Before December 7

Medicare Open Enrollment is one of the most important times of the year for people who already have Medicare. From October 15 through December 7, 2026, Medicare beneficiaries have an opportunity to review their current coverage and make changes for 2027. Any coverage changes made during this period generally take effect on January 1, 2027. Even if you are satisfied with your current plan, taking time to review your coverage can be worthwhile. Medicare Advantage and prescription drug plans can change from year to year—including premiums, provider networks, prescription drug coverage, copays, deductibles, and additional benefits. Here are seven areas worth reviewing before making your Medicare decisions for 2027. 1. Review Your Current Plan’s Changes for 2027 One of the biggest Medicare mistakes is assuming that because a plan worked well this year, it will automatically work the same way next year. Plans may change their: Monthly premiums Deductibles Copayments

Before Your Next Appointment: 5 Medicare Questions That Can Help Prevent Costly Surprises

You schedule an appointment, hand over your insurance card, and assume your coverage will take care of the rest. Then a bill arrives—or the pharmacy tells you that your new prescription needs approval. Understanding your Medicare coverage before you use it can help you prepare for expenses, address paperwork, and ask better questions. Whether you are new to Medicare or have had coverage for years, these five questions are worth keeping handy. 1. Can I Use This Doctor With My Coverage? “Do you take Medicare?” is a starting point, but the next question depends on how you receive your benefits. With Original Medicare, you can generally use doctors and hospitals that accept Medicare throughout the United States. Ask whether the provider accepts assignment, meaning they agree to accept the Medicare-approved amount as full payment for covered services. With Medicare Advantage, you may need to use your plan’s network for non-emergency

7 Medicare Enrollment Mistakes to Avoid When Turning 65

Turning 65 is an exciting milestone—but it also brings important Medicare decisions. With multiple enrollment periods, coverage options, and deadlines to understand, even a small mistake could lead to delayed coverage, unexpected expenses, or lifelong penalties. Here are seven common Medicare enrollment mistakes and how you may be able to avoid them. 1. Assuming Medicare Enrollment Is Always Automatic Some people are automatically enrolled in Medicare Parts A and B, while others must enroll themselves. If you are already receiving Social Security or Railroad Retirement Board benefits before turning 65, enrollment may happen automatically. If you are not receiving these benefits, you will generally need to sign up for Medicare. Do not assume your coverage will begin automatically. Confirm your enrollment status before your 65th birthday. 2. Missing Your Initial Enrollment Period Your Medicare Initial Enrollment Period is a seven-month window that generally includes: The three months before your 65th
