Annual Medicare Participation Open Enrollment

The Annual Medicare Participation Open Enrollment Period (mid-November through December 31) is your opportunity to decide if you want to participate in Medicare for the upcoming year.

Medicare "participation" means you agree to accept Medicare-allowed amounts as payment in full for all Medicare-covered services to your patients.

See the information below to help you determine if you want to continue or become a Medicare-participating provider.

Note: No action is required if you aren't changing your current participation status.
