* Plans F and G also offer a high-deductible plan in some states. With this option, you must pay for Medicare-covered costs (coinsurance, copayments, and deductibles) up to the deductible amount of $2,870 in 2025 before your policy pays anything. (Plans C and F aren't available to people who were newly eligible for Medicare on or after January 1, 2020.)
** For Plans K and L, after you meet your out-of-pocket yearly limit and your yearly Part B deductible, the Medigap plan pays 100% of covered services for the rest of the calendar year.
*** Plan N pays 100% of the Part B coinsurance, except for a copayment of up to $20 for some office visits and up to a $50 copayment for emergency room visits that don't result in inpatient admission.
Medicare Supplement plans are sold by private insurance companies, so prices, or premiums, can vary. There can be differences in the premiums that different insurance companies charge for exactly the same coverage.
Costs that you pay with any Medigap plan include:
You can apply for a Medicare Supplement plan any time. However, the best time to buy a Medigap plan is during your 6-month Medicare Supplement Open Enrollment Period.
Your Medicare Supplement Open Enrollment Period starts the first month you have Part B and you're age 65 or older. The big advantage is you can buy any Medicare Supplement plan sold in your state without medical underwriting. So even if you have health problems, you can buy any Medicare Supplement plan for the same price as people with good health during this time period.
Some states have additional Open Enrollment Periods including those for people under age 65.
Everyone has unique healthcare needs. When choosing between Medigap plans, ask yourself questions like:
