Why A is correct
Enrollment in a Medicare Advantage plan requires that the beneficiary be entitled to Part A and enrolled in Part B, and reside in the plan's service area. MA plans assume responsibility for delivering Part A and Part B benefits, so both parts must be in effect. The requirement is a basic condition of Part C participation and is commonly tested alongside the plan-type material under AH-III.D.1f. Without both parts in place, the plan could not provide the full Medicare benefit package it is required to deliver.
Why the other options are wrong
- B) Part D is often included in an MA plan, but enrolling in a separate stand-alone PDP first is not an enrollment condition.
- C) Medicare Supplement policies cannot be used with Medicare Advantage; owning one is not an enrollment requirement.
- D) SSDI history is not an enrollment condition for MA; age-65 entitlement with Parts A and B suffices.
Memory hook
Medicare Advantage needs both Part A and Part B to enter.
