Answer:
A Medicare Prescription Drug Plan.
Step-by-step explanation:
This type of plan focuses on providing a standalone drug coverage to Medicare plans that an individual already subscribes to. Each Medicare Plan encompasses these four parts: Part A (Hospital Insurance) and Part B (Medical Insurance) through Part C (Medicare Advantage Plans), and Part D (Prescription Drugs).
The Medicare Prescription Drug Plan is available for individuals who have subscribed to the original Medicare plan (either or both Part A and B), the Medicare Medical Savings Account Plan, and some types of Medicare Cost Plan and Medicate Private-Fee-For-Services Plans.
Individuals who have Part C are covered with Part D, however, Part C includes other medical services not covered by Part A and B such as vision, hearing, and dental. Thus, since Eleanor only wants a plan that covers prescription drug only, she should add the Medicare Prescription Drug Plan to her current Medicare package.
