The Medicare Supplement free look period is a 30-day window, starting when you receive a new Medigap policy, during which you can return it and get your premium back for any reason. If you are replacing an older policy, keep paying the old one until you decide, because you will owe both premiums for the month they overlap.

Buying a Medigap policy is a big decision, and sometimes the paperwork looks different once it arrives in your mailbox. State insurance laws give you a short window to read the actual contract and back out with a refund if it is not what you expected. That window is the free look period.
This page explains when the 30 days start, what the refund covers, how the period works when you swap one policy for another, and where state laws add extra protection. If you are thinking about changing plans, also read whether you can switch Medicare Supplement plans before you apply.
