Medicare Supplement (Medigap) Plans in New York: What Makes New York Different
A Medicare Supplement, or Medigap, plan fills the gaps in Original Medicare. New York has some of the most consumer-friendly Medigap rules in the country, which matters a great deal when an insurer leaves the market. This guide covers how the plans work, the New York rules, and what to compare.

What a Medicare Supplement pays
Original Medicare pays most of the cost of covered hospital and medical care, but it leaves deductibles, coinsurance, and copays for you to pay, with no annual limit. A Medicare Supplement is a private policy that pays some or all of those leftover costs. You use it alongside Original Medicare, and it works with any doctor or hospital in the United States that accepts Medicare, with no network and no referrals.
Medigap plans sold today do not include prescription drug coverage, so you will usually want a standalone Part D plan as well.
The lettered plans
Medigap plans are standardized by letter (A, B, C, D, F, G, K, L, M, and N). A Plan G from one insurer has the same standard benefits as Plan G from another insurer. Some companies add small extras, such as a fitness program or nurse line. The main differences are the premium and the company's service and rate history. Plans C and F, which cover the Part B deductible, are only available to people who became eligible for Medicare before January 1, 2020, so many people new to Medigap today compare Plan G and Plan N.
Why New York is different
- Continuous open enrollment: New York requires Medigap insurers to accept applicants at any time of year, regardless of health history. There is no medical underwriting and no waiting for a special window.
- Community rating: New York Medigap premiums do not vary by age, so a 78-year-old pays the same rate as a 65-year-old for the same plan from the same company.
- Limited Part B excess charges: a doctor who does not accept Medicare assignment can bill more than the Medicare-approved amount, but New York caps the extra at 5% for most services, and the federal 15% cap applies to certain office and home visits. The excess-charge exposure that Plan N carries is limited here, not eliminated.
- One caution: an insurer may apply a waiting period of up to six months for pre-existing conditions if you did not have prior creditable coverage. Prior coverage, including a Medicare Advantage plan that is ending, counts toward reducing or eliminating that wait, as long as you had no break in coverage longer than 63 days.
- Federal law separately gives you a guaranteed-issue right to certain Medigap plans if your Medicare Advantage plan leaves Medicare or stops serving your area and you switch to Original Medicare. The window opens when you receive the plan's termination notice and closes 63 days after your coverage ends, which by our count is March 4, 2027 for a plan ending December 31, 2026. Inside that window, no pre-existing condition waiting period can apply.
Medigap plus Part D
Because Medigap has no drug coverage, choose a standalone Part D plan with the same start date. Going without creditable drug coverage for 63 days or more can add a late enrollment penalty to your Part D premium.
What to compare
- The premium for the same lettered plan across companies, since the standard benefits are the same by law.
- Each company's history of rate increases. Community rating means your premium does not rise because you age, but it can rise for everyone on the plan.
- Plan G (very little out of pocket) versus Plan N (small copays for office and emergency visits). Plan N usually costs less, but not at every company, so compare both.
- Any household or other discounts the company offers, and how claims and customer service are handled.
Is a Supplement the right move if your Medicare Advantage plan is not renewed?
If your Medicare Advantage plan is ending, this is a natural moment to consider Original Medicare with a Supplement, because New York insurers cannot turn you down or charge you more because of your health, and it lets you keep any doctor who accepts Medicare. The trade-off is a separate monthly premium for the Supplement, plus the need for a separate drug plan. A licensed agent can put the two paths next to each other with your doctors and prescriptions filled in.
