Rating Medicare Supplement Plans For 2026
Choosing the right Medicare supplement plan in 2026 can save you thousands while keeping your care flexible and predictable.
In this guide, you’ll learn what Medicare Supplement (Medigap) plans are, the five highest rated options experts most often recommend, how they differ, and how to pick the right fit for your budget and health needs.What are Medicare Supplement (Medigap) plans?
Medicare Supplement (also called Medigap) policies are private insurance plans that work alongside Original Medicare (Parts A and B) to pay some or all of the “gaps” like deductibles, copays, and coinsurance. They don’t replace Medicare and they don’t include drug coverage—pair a Part D plan for prescriptions. See the official overview and plan chart on Medicare.gov.
Medigap benefits are standardized by law in nearly every state: lettered plans (A–N) from any insurer must cover the same core benefits—only the monthly premium and service vary. For example, a Plan G from one company covers the same medical benefits as a Plan G from another. Note: Plan F (and high-deductible F) aren’t available to people newly eligible for Medicare on or after January 1, 2020.
Timing matters. Your six‑month Medigap Open Enrollment Period starts the month you’re 65 or older and enrolled in Part B; during this window you can buy any plan sold in your area with no health questions in most states. Outside that window, you may face medical underwriting unless you have a guaranteed‑issue right.
The 5 highest rated Medicare supplement plans in 2026
There’s no official government star rating for Medigap like there is for Medicare Advantage or Part D. Instead, consumer advocates and Medicare educators consistently highlight a handful of standardized plan letters as the top choices based on coverage value, popularity, and simplicity. The list below reflects widely cited guidance from sources like Medicare.gov, state SHIP counselors, and nonpartisan research from KFF.
- Plan G — Best overall for new enrollees
Most comprehensive option available to people new to Medicare. Covers Part A hospital costs, Part B coinsurance, skilled nursing coinsurance, blood, Part A deductible, and Part B excess charges; it does not cover the Part B deductible. Premiums are typically higher than Plan N but lower than Plan F (for those eligible). Fits people who want predictable costs and extensive coverage. - Plan N — Best value for many retirees
Lower monthly premiums than Plan G, with small copays (up to $20 for office visits and up to $50 for ER if not admitted). Does not cover Part B excess charges, so it works best where providers accept Medicare assignment or in states that limit/banned excess charges. Great for healthy beneficiaries comfortable with occasional copays. - High‑Deductible Plan G — Lowest premium, safety‑net benefit
Same benefits as Plan G after you meet an annual high deductible set by CMS each year. Premiums are typically much lower, but you’ll pay most Medicare‑covered costs until reaching that deductible. Good for budget‑minded buyers who can handle higher early‑year expenses. - Plan F (if eligible) — Most comprehensive
Covers everything Plan G covers plus the Part B deductible, making near‑zero out‑of‑pocket for Medicare‑approved services. Only available if you were Medicare‑eligible before 1/1/2020 or in certain states with special rules. Usually carries the highest premiums; compare against Plan G to ensure the extra premium outweighs the saved deductible. - Plan K — Budget pick with annual out‑of‑pocket limit
Covers 50% of many Part A and B cost‑shares until you hit an annual out‑of‑pocket maximum (set by CMS and updated yearly), then pays 100% for the rest of the year. Premiums are among the lowest. Best for healthy enrollees who want protection from worst‑case costs but are comfortable sharing routine expenses.
Key differences among the top plans
1) Premiums vs. pay‑as‑you‑go costs
- Plan G: Higher premium, minimal bills at point of care (except the Part B deductible).
- Plan N: Lower premium, modest copays and no coverage for Part B excess charges.
- High‑Deductible G: Very low premium, but you pay Medicare‑covered costs until the annual deductible is met.
- Plan F: Highest premium, near‑zero bills for covered services.
- Plan K: Low premium with 50% cost‑sharing until the plan’s annual out‑of‑pocket limit is reached.
2) Excess charges and provider choice
Original Medicare lets you see any provider nationwide who accepts Medicare. Plans G and F cover Part B excess charges (up to 15% above the Medicare‑approved amount where allowed), while Plan N does not. In many areas, most providers accept assignment, limiting how often excess charges appear. Learn how assignment works on Medicare.gov.
3) Out‑of‑pocket limits and deductibles
Only Plans K and L (not listed here except K) include an annual out‑of‑pocket maximum—valuable if you want a cap on worst‑case spending. High‑Deductible G shifts more early‑year risk to you but can save significantly in premium if you rarely use care. Annual deductible and OOP maximum amounts are set by CMS; check the current figures on the Medigap plan chart.
4) Enrollment and underwriting rules
Apply during your six‑month Medigap Open Enrollment Period or when you have a qualifying guaranteed‑issue event to avoid medical underwriting in most states. Outside those times, switching plans can require health questions and could lead to a denial or higher premium.

How to choose the right plan in 5 steps
- Estimate usage: If you see specialists often or anticipate procedures, Plan G or F (if eligible) can reduce surprises. If you mostly have checkups, Plan N or High‑Deductible G may be sufficient.
- Check provider billing habits: If your doctors accept assignment consistently, Plan N’s lack of excess‑charge coverage may be a non‑issue. If not, favor G or F.
- Decide your risk tolerance: Prefer a lower fixed premium and can handle early bills? Consider High‑Deductible G or K. Want fewer bills later? Consider G or F.
- Shop multiple insurers: Quotes for the same letter vary widely. Compare companies’ rate histories and discounts; use Medicare’s Medigap policy search tool and ask a local SHIP counselor for unbiased help.
- Understand pricing methods: Community‑rated, issue‑age, and attained‑age pricing affect how premiums change over time. Learn the differences on Medicare.gov.
Important reminders
- Medigap vs. Medicare Advantage: These are different paths. Medigap works with Original Medicare and has no provider networks; Medicare Advantage replaces Original Medicare with a private plan that may have networks and managed care rules.
- Drug coverage: Add a standalone Part D plan for prescriptions; Medigap does not include drugs.
- Foreign travel: Some Medigap plans include limited foreign travel emergency coverage (typically 80% up to a lifetime cap). Always verify the current limits on the official chart.
- State rules vary: A few states standardize plans differently or offer unique rights (for example, year‑round switching). Check with your state’s SHIP or insurance department.
Bottom line
If you’re new to Medicare in 2026, Plan G is the most comprehensive widely available option, while Plan N often provides the best balance of premium and protection. High‑Deductible G and Plan K can trim premiums if you’re comfortable with more cost‑sharing, and Plan F remains the gold standard for those who still qualify. Compare quotes for the same letter from multiple insurers, apply during your open‑enrollment or guaranteed‑issue window, and use trusted resources like Medicare.gov and your local SHIP to make a confident choice.
