Special Election Period

A set time that a beneficiary can change health plans or return to the Original Medicare Plan, such as: you move outside the service area, your Medicare+Choice organization violates its contract with you, the organization does not renew its contract with CMS, or other exceptional conditions determined by CMS. The Special Election Period is different from the Special Enrollment Period (SEP). (See Election Periods; Enrollment; Special Enrollment Period (SEP).)
