Medicare Advantage Enrollment in California

When To Enroll For A Medicare Advantage Plan

You can sign up for a Medicare Advantage plan (also known as Medicare Part C) when you first become eligible for Medicare. There are also other times during the year when you can change your Medicare Advantage plan. For the most part, unless you are signing up for Medicare for the first time, Medicare Advantage enrollment periods occur at specific times throughout the year.
