Answer & full 3-part explanation (select an option above, or peek)
Why A is correct
Part D is voluntary coverage available to anyone entitled to Part A and/or enrolled in Part B. A person may obtain drug coverage either through a stand-alone Prescription Drug Plan (PDP) or through a Medicare Advantage plan that includes drug coverage (MAPD). Enrollment in a Medigap plan or an MA plan is not a precondition for Part D.
Why the other options are wrong
- B) Part D is available through stand-alone PDPs for people in Original Medicare; an MA plan is not required.
- C) There is no age-55 threshold; the requirement is Part A entitlement and/or Part B enrollment.
- D) A Medigap policy is not required for Part D; in fact, Medigap plans do not include drug coverage.
Memory hook
Part D's entry ticket: a Medicare card (Part A and/or B). No MA, no Medigap, no age-55 test.
