Final answer:
Medicare prescription drug plans are required to cover drugs in each therapeutic category. Mrs. Allen should be able to find a plan that covers the medications she needs.
Step-by-step explanation:
The correct answer is 1) Medicare prescription drug plans are required to cover drugs in each therapeutic category. She should be able to enroll in a Medicare prescription drug plan that covers the medications she needs.
Under Medicare Part D, prescription drug plans are required to provide coverage for at least two drugs in each therapeutic category. This means that Mrs. Allen should be able to find a Medicare prescription drug plan that covers at least one of the two brand name drugs she needs for her rare condition.
It's worth noting that the availability and cost of specific medications may vary depending on the individual plan and its formulary, so Mrs. Allen should carefully review her options to ensure that the plan she chooses covers the specific drugs she needs.
