Starting 2019, the Center for Medicare and Medicaid Services (CMS) restored the Medicare Advantage (MA) Open Enrollment Period (OEP). The MA OEP will begin January 1 and run through March 31 of each year. Medicare Advantage members are allowed to make a one-time election to switch to another Medicare Advantage Plan (with or without Part D drug coverage) or to return to Original Medicare (with or without Part D drug coverage).
What, when, who?
When is OEP?

For newly MA-eligible individuals, the OEP occurs the first 3 months in which they have both Part A and Part B.
Who can use OEP?
Individuals enrolled in an MAPD plan or an MA-only plan.
What changes can be made during OEP?
Individuals enrolled in an MAPD plan can use the OEP to make a one-time change to a different MAPD plan, an MA-only plan, or Original Medicare (with or without a PDP).
Individuals enrolled in an MA-only plan can use the OEP to make a one-time change to a different MA-only plan, an MAPD plan, or Original Medicare (with or without a PDP).
