Which of the following covers prescription drugs for Medicare beneficiaries?

Medicare Part D is specifically designed to provide coverage for prescription drugs for Medicare beneficiaries. It was established to help individuals afford medications by offering a range of private insurance plans that are approved by Medicare. Beneficiaries can sign up for Part D during designated enrollment periods, and the plans vary in costs and the list of covered drugs, known as the formulary.

Part A primarily covers inpatient hospital stays, skilled nursing facility care, hospice care, and some home health care; it does not include prescription drug coverage for medications obtained outside of these settings. Part C, also known as Medicare Advantage, bundles various Medicare benefits including Parts A and B, and may offer additional coverage such as vision and dental, but it does not guarantee prescription drug coverage, as that depends on the specific plan chosen. Part E is not a recognized part of the Medicare program.

The distinction of Part D as the correct choice hinges on its explicit focus on outpatient prescription medications, making it an essential aspect of healthcare for those enrolled in Medicare who need help managing the costs of their prescriptions.
