When Can You Enroll?

There are enrollment timeframes and qualifications for Medicare Supplement plans. Medicare Supplement insurance companies are generally allowed to use medical underwriting to decide whether to accept your application and how much to charge you for the plan, unless you enroll during your initial open enrollment period or you qualify for a “guaranteed issue”.

  • Your open enrollment period begins on the first day of the month in which you’re both 65 or older and enrolled in Medicare Part B.
    (Some states may offer plans for people under age 65 and enrolled in Part B.)
  • In most cases, you have guaranteed issue rights for the following:
  • You lose other health care coverage.
  • You are in your Medicare Advantage trial period and change your mind.
  • Oregon “Birthday Rule” allows you to switch from one Medigap plan to another with same or lesser benefits, for 30 days starting on your birthday.
