Find your 6-month Medigap open enrollment window, the one time insurers can't deny you or charge more for health reasons.
Educational estimate. Premiums vary by insurer, age, location and rating method.
Your Medigap Open Enrollment Period is the 6 months starting when your Medicare Part B begins. We compute the exact window from your Part B start.
For six months starting when your Part B begins, you have a guaranteed right to buy any Medigap plan at the best price, regardless of your health. After it closes, insurers in most states can make you answer health questions and can deny you or charge more. This single window is why timing your Medigap purchase matters more than almost any other Medicare decision.
The 6 months beginning the month your Part B coverage starts (and you're 65+).
It's the only guaranteed-issue window — no medical underwriting, no denials.
Insurers can use medical underwriting to deny coverage or charge more.
