Medicare Supplement Plans for 2026: 5 Picks

Choosing the right Medicare supplement plan in 2026 doesn’t have to be confusing.

In this guide, we’ll break down the five best Medigap options, the trade-offs to consider, and a simple process to pick the plan that fits your budget and healthcare needs.

The 5 best Medicare supplement plans in 2026

Medicare supplement (Medigap) plans are standardized by letter in most states, so a Plan G from one insurer covers the same benefits as a Plan G from any other—only premiums, rate increases, discounts, and underwriting differ. See the standard Medigap benefits chart on Medicare.gov for details.

If you became eligible for Medicare on or after January 1, 2020, Plans C and F generally aren’t available to you, which is why Plan G and Plan N dominate new enrollments. There’s also a high-deductible version of Plan G in many states, with the deductible amount set annually by CMS. Learn more about availability and coverage rules on the official Medigap overview.

Premiums vary by ZIP code, age, tobacco use, and how your carrier “rates” policies (community-rated, issue-age, or attained-age). Review how Medigap pricing works here: Medigap costs explained.

  1. Plan G — The most comprehensive option for people new to Medicare after 2020. It covers all Original Medicare gaps except the Part B deductible.

    • Pros: Broadest protection for new enrollees; covers Part A hospital deductible, skilled nursing facility coinsurance, Part B coinsurance/copays, and Part B excess charges; nationwide acceptance with any provider who takes Medicare.
    • Cons: Typically one of the higher premium options; you still pay the annual Part B deductible; premiums can rise over time.
    • Best for: Frequent healthcare users, snowbirds or travelers, and anyone who wants predictable out-of-pocket costs.

  2. Plan N — A value-forward alternative to G with lower premiums in exchange for modest cost-sharing.

    • Pros: Often significantly lower monthly premiums than Plan G; covers the big-ticket items (hospital deductible, Part B coinsurance) while keeping ongoing costs manageable.
    • Cons: Up to small copays for certain office and ER visits; does not cover Part B excess charges (charges above the Medicare-approved amount) if a provider doesn’t accept assignment; still doesn’t cover the Part B deductible.
    • Best for: People comfortable with occasional copays who mainly see in-network providers that accept Medicare assignment.

  3. High-Deductible Plan G — Ultra-low premiums with a higher annual deductible that you must meet before most Medigap benefits pay. The deductible amount is indexed annually.

    • Pros: Among the lowest monthly premiums; full Plan G benefits apply after you meet the annual high deductible; good fit for those who want catastrophic protection.
    • Cons: You shoulder more upfront risk each year; budget discipline is key to cover the deductible if a major event occurs; not offered by all insurers in all ZIP codes.
    • Best for: Generally healthy enrollees who want the safety net of Plan G but prefer to minimize monthly costs.

  4. Plan D — Similar to Plan G but does not cover Part B excess charges. It keeps strong inpatient and outpatient coverage while trimming premium in markets where excess charges are uncommon.

    • Pros: Often priced below Plan G; covers the Part A deductible, skilled nursing facility coinsurance, and Part B coinsurance; includes foreign travel emergency coverage (like Plan G and N) up to the policy limits.
    • Cons: No coverage for Part B excess charges—if a provider bills above Medicare’s approved amount, you may owe the difference; availability varies by insurer and state.
    • Best for: Areas where providers commonly accept Medicare assignment and excess charges are rare; enrollees who vet their doctors in advance.

  5. Plan K — A budget-conscious, cost-sharing option that covers 50% of certain benefits and includes an annual out-of-pocket maximum for Medicare-approved services.

    • Pros: Lower monthly premiums; you share costs (50%) for many services until you hit the plan’s annual out-of-pocket limit, after which Medigap pays 100% for the rest of the year.
    • Cons: More cost exposure at the point of care; does not cover Part B excess charges; fewer carriers offer it compared to G or N.
    • Best for: Price-sensitive shoppers who want a hard cap on worst-case costs and can handle cost-sharing for routine care.

How to choose the right Medigap plan in 2026

1) Map your expected care and provider preferences

  • List your doctors, specialists, and likely services. If your clinicians accept Medicare assignment, the risk of Part B excess charges is low. Learn what excess charges are here: Medicare excess charges.
  • Travel often? Plans G, N, and D typically include limited foreign travel emergency coverage. Verify specifics in the Medigap coverage chart.

2) Decide your premium vs. risk trade-off

  • If you want near-complete predictability, Plan G is the benchmark.
  • If you’re comfortable with small copays, consider Plan N to cut premiums.
  • If you prioritize the lowest premium and can budget for a larger deductible, High-Deductible G may fit.
  • If you live where excess charges are rare, Plan D can be a savvy middle ground.
  • If you want a safety cap with lower premiums, evaluate Plan K’s out-of-pocket maximum.

3) Compare prices the right way

  • Get quotes from multiple carriers—benefits are standardized, but prices aren’t. Use Medicare’s official tool to explore options by ZIP: Find Medigap policies.
  • Ask carriers about household or autopay discounts, and review their historical rate increases.
  • Understand pricing methods: community-rated (same for all ages), issue-age (based on age when you buy), and attained-age (rises as you get older). See how Medigap costs work.

4) Time your enrollment to protect your rights

  • Your six-month Medigap Open Enrollment Period starts when you’re 65+ and enrolled in Part B—this is the easiest time to buy because carriers generally can’t deny you or charge more due to health status. Review the rules: When can I buy Medigap?
  • You may also have guaranteed issue rights after certain events (for example, losing employer coverage). Learn more: Guaranteed issue rights.
  • Outside protected windows, many states allow medical underwriting. If you plan to switch plans later, factor in your health history and medication list.

Other 2026 considerations worth noting

  • Medigap doesn’t include drug coverage. Pair your Medigap plan with a Part D prescription plan that matches your medications and pharmacy preferences. Compare options on the official tool: Medicare Plan Compare.
  • Foreign travel emergency benefits have limits. Plans that offer this benefit typically pay 80% for emergencies abroad up to lifetime caps after a small deductible—review policy fine print before international trips.
  • Provider choice is broad with Medigap. Any doctor or facility that accepts Medicare is usually in play—no referrals required, and no networks like many Medicare Advantage plans.
  • State rules can differ. A few states standardize Medigap differently or have special protections. When in doubt, contact your local State Health Insurance Assistance Program (SHIP): SHIP counseling is free and unbiased.
  • Budget for the Part B deductible. Plans G, N, D, and K do not cover the annual Part B deductible; this amount can change each year.
  • If you were eligible before 2020 and still have Plan F or C, you can keep it. People newly eligible after 2020 generally can’t buy F or C. Details: Medigap coverage chart.

Quick decision guide

  • Want the broadest coverage and simplicity? Choose Plan G and budget for the Part B deductible.
  • Want a lower premium and don’t mind small copays? Choose Plan N.
  • Prefer the lowest premium with a bigger safety valve? Choose High-Deductible G.
  • Live where doctors typically accept assignment? Consider Plan D to save versus G.
  • Need a cap on costs but want to pay less per month? Consider Plan K.
