Why A is correct
Part D eligibility requires the beneficiary to be entitled to Part A and/or enrolled in Part B. A person entitled to Part A can join a standalone prescription drug plan (PDP), and so can a person enrolled in Part B. Part D does not require a Medigap policy, and it is not limited to those in Medicare Advantage — indeed, Medicare Advantage plans with drug coverage (MAPDs) are themselves one delivery form of Part D. Understanding who may enroll is the threshold question in every Part D sale.
Why the other options are wrong
- B) A beneficiary with Original Medicare may enroll in a standalone PDP; Part D is not restricted to Medicare Advantage members, so this option adds a requirement the law does not impose.
- C) There is no age-70 requirement; Part D eligibility tracks Part A entitlement or Part B enrollment, so this option invents an age threshold the program never uses.
- D) Medigap is unrelated to Part D eligibility; the two are separate products, so this option wrongly links drug coverage to a supplement policy.
Memory hook
Part D's ticket in: Part A entitlement or Part B enrollment. Medigap and age 70 have nothing to do with it.
