Medicare Supplement Plan M vs Plan N — 2026 Comparison
Compare Plan M and Plan N: both have lower premiums than Plan G, but differ in how they handle the Part A deductible, copays, and excess charges.
Plan M covers 50% of the Part A deductible and does not have office visit copays. Plan N covers the full Part A deductible but has up to $20 office visit copays. Plan M is rare in the market — not all insurers offer it — while Plan N is widely available.
Plan M vs Plan N: Side-by-Side Comparison
Both Plan M and Plan N are federally standardized Medicare Supplement (Medigap) plans. Every insurer that sells these plans must provide identical benefits — the only variable is the monthly premium. The table below highlights where the two plans differ.
| Feature | Plan M | Plan N |
|---|---|---|
| Part A deductible ($1,676 in 2026) | 50% covered | Fully covered |
| Doctor visit copay | No copay | Up to $20 |
| Part B excess charges | Not covered | Not covered |
| Market availability | Rare — few insurers offer it | Widely available |

What Plan M Covers
Plan M provides comprehensive coverage similar to Plan D, but requires you to pay 50% of the Part A deductible rather than having it fully covered. It fully covers Part B coinsurance, skilled nursing facility coinsurance, and foreign travel emergencies. Plan M does not cover the Part B deductible or Part B excess charges. Plan M is relatively rare and not offered by all insurers.

What Plan N Covers
Medicare Supplement Plan N is the second most popular Medigap plan.

Who Should Choose Plan N?
Most beneficiaries who want comprehensive coverage at premiums below Plan G — Plan N is far more commonly available.
Annual Cost Analysis: Plan M vs Plan N
Because Medigap plan benefits are standardized, choosing between Plan M and Plan N is primarily a financial decision. The right plan depends on how much healthcare you use and your comfort with out-of-pocket exposure vs. higher monthly premiums.
To do your own cost analysis, estimate your annual healthcare usage (number of doctor visits, specialist visits, potential hospitalizations) and multiply the copays or cost-sharing amounts by those estimates. Add your annual premium. Compare the totals.
Important: premium savings in good health years are real money now. But a major illness or hospitalization can quickly make the more comprehensive plan worth it. Consider your health history and risk tolerance.
How to Get the Best Rate
Because benefits are standardized, the only reason to choose one insurer over another is the premium and the company's premium increase history. Follow these steps:
- Decide between Plan M and Plan N based on the cost analysis above.
- Get quotes from multiple insurers for the plan letter you've chosen. Use Medicare.gov's Plan Finder or a licensed broker who works with multiple companies.
- Compare premium increase history. Ask insurers for rate increase data for the past 3–5 years. A lower starting premium is worth less if it rises aggressively each year.
- Enroll during your Open Enrollment Period if possible — the 6-month window starting when you're both 65+ and enrolled in Medicare Part B. During this window, you have guaranteed issue rights and cannot be denied or charged more based on health conditions.
- Consider free SHIP counseling — State Health Insurance Assistance Program counselors are trained volunteers who don't sell insurance and can help you compare options. Find your local SHIP at shiphelp.org.
Frequently Asked Questions
Why is Plan M so hard to find?
Plan M is federally standardized but insurers are not required to offer every plan letter. Most insurers focus on Plans G and N due to high market demand, and Plan M occupies a narrow niche between them. A licensed broker can help you find insurers offering Plan M in your state if you want to explore it.
