What is Medicare Supplement Insurance?
Medicare Supplement Insurance, commonly known as Medigap, is an insurance policy designed to help pay for certain out-of-pocket costs not covered by Original Medicare (Parts A and B). This can include deductibles, copayments, and coinsurance, making health expenses more predictable during retirement. Offered by private insurance companies, Medigap plans are standardized by the federal government into plans labeled A through N. This means each plan letter provides the same benefits no matter which insurer sells it, though premiums, discounts, and added features can vary.
Medigap coverage works by paying its share after Medicare pays its approved portion of healthcare costs. Policyholders must pay a monthly premium for their Medigap plan, in addition to their Medicare Part B premium. For a detailed look at what Medicare Part B covers and its costs, see our resource on Medicare Part B.
Medigap policies are guaranteed renewable as long as premiums are paid on time and honest information is provided at enrollment. These plans can empower enrollees to manage expenses and access care from any doctor or hospital that accepts Medicare, making them particularly valuable for frequent travelers or retirees residing in multiple states.

Most Popular Plans Explained
The 2026 Medigap market is dominated by a handful of plans that balance monthly premiums, out-of-pocket predictability, and flexible doctor access. Here’s how the top choices stack up:
Plan G: Most Comprehensive for New Enrollees
- Covers all out-of-pocket costs except the Part B deductible ($240 in 2026).
- Includes Part A deductible, coinsurance, excess charges, foreign travel emergency care.
- Available in standard or high-deductible format (HDG, $2,950 annual deductible).
- Rate stability and national coverage make Plan G the best Medigap plan for most enrollees in 2026.
Wondering is Plan G the best Medigap plan? For nearly all new enrollees, the answer is yes due to near-full coverage and wide acceptance.
Plan N: Lower Premiums-Some Cost Sharing
- Lower monthly premiums than Plan G, but you pay up to $20 copay per office visit and up to $50 per ER visit (no hospital admission), plus the Part B deductible.
- Appealing for enrollees who visit the doctor less often and want to save monthly.
For more detail or to start enrollment, see our article Medicare Part N Coverage: Benefits, Costs & How to Enroll.
Plan F: Legacy Coverage (If Eligible)
- The only plan (besides High-Deductible F) that covers Part B deductible and all excess charges (not available to those eligible for Medicare after January 1, 2020).
- Premiums tend to be higher, and rate increases have been steeper post-2020, but it’s the gold standard for those who qualify.
If you’re newly eligible, your best option is typically Plan G vs Plan N. Plan G wins for peace of mind and nearly complete coverage; Plan N wins for lower premiums if you’re comfortable with some cost-sharing.
Other Plans: K, L, and M
- Plans K and L have lower premiums, out-of-pocket limits ($8,000 and $4,000 respectively in 2026), and are good for those comfortable splitting more of their care costs until limits are met.
- Plan M splits the Part A deductible, but otherwise covers basic Medigap benefits. Rare, but sometimes cost-effective in select states.

Choosing the best Medicare Supplement plan 2026 starts with understanding your preferences and needs, then comparing actual rates by location and company.

- Factor in overall costs: Lower premiums may come with higher out-of-pocket costs (as in Plan N and Plan K/L).
