The Medicare Advantage Open Enrollment period runs from Jan. 1 through March 31. During this period each year, consumers can switch from their Medicare Advantage Plan (excluding Medical Savings Accounts, cost plans, and PACE) to another Medicare Advantage Plan, or to Original Medicare with or without a Part D plan. They can only use this enrollment period if they have a Medicare Advantage Plan. If consumers signed up for Part A and/or Part B because of an exceptional situation, they’ll have two months to join a Medicare Advantage Plan (with or without drug coverage) or a Medicare drug plan (Part D). The coverage will start the first day of the month after the plan receives the request to join.
