Under the MA Open Enrollment Period, which action is allowed?

• A. Switch from one MA plan to another MA plan or switch to Original Medicare with/without a PDP
• B. Enroll in a PDP only
• C. Switch from Original Medicare to Medicaid
• D. Cancel Medicare entirely and enroll in a non-Medicare plan

Answer: (A)

During the Medicare Advantage Open Enrollment Period, someone already enrolled in a Medicare Advantage plan can change their coverage in one of two ways: switch to a different Medicare Advantage plan, or switch back to Original Medicare and join a standalone prescription drug plan if they want one. This period is specifically for MA enrollees to adjust their plan selections mid-year without waiting for the next annual enrollment. It does not allow enrolling in a PDP alone without reverting to Original Medicare, and it does not allow moving to Medicaid or canceling Medicare for a non‑Medicare plan. So the permitted action is switching between MA plans or returning to Original Medicare with/without a PDP.
