When can I change my participation status?
Toward the end of each calendar year there is an open enrollment period, generally from mid-November through December 31. During this period, if you’re enrolled in the Medicare Program, you can change your current participation status beginning Jan. 1 of the next calendar year. The open enrollment period is the only opportunity to change your participation status.
New physicians, practitioners, and suppliers can sign the participation agreement at the time of enrollment and become a Medicare participating provider in the Medicare Program. The participation agreement will become effective on the date of filing (i.e., the date the participant mails [postmark date] the agreement to the MAC).
If you participate in the Medicare program, you must accept assignment on all claims. Non-participating providers can elect to accept assignment or not accept assignment on a claim-by-claim basis. While you make this decision upon initial enrollment or during the open enrollment period, there are providers that are required to accept assignment.
Medicare requires the following practitioners accept assignment for all services rendered to Medicare beneficiaries:
Physician assistant
Nurse practitioner
Certified registered nurse anesthetist
Clinical nurse specialist
Certified nurse midwife
Clinical social worker
Clinical psychologist
Registered dietician/nutrition professional
Anesthesiologist assistant
Mass immunization roster billers
Because these practitioners must accept assignment on claims, it is not necessary to complete a participation agreement when enrolling in the Medicare program.
