Medicare Part D primarily reimburses for which service?

Medicare Part D is specifically designed to provide prescription drug coverage to beneficiaries. Under this program, enrollees can obtain necessary medications through a network of approved providers and pharmacies. The intention behind Part D is to reduce the costs associated with obtaining prescription medications, helping to ensure that seniors and individuals with disabilities can maintain their health by having access to essential drugs.

Preventive health care services, while important, fall under different segments of Medicare (such as Part A and Part B), focusing on wellness checks and preventive screenings rather than direct drug reimbursement. Alcohol misuse counseling can be covered under certain conditions, but it is not the primary focus of Medicare Part D. Additionally, over-the-counter drugs are generally not covered by Part D, since the program is geared specifically towards prescription medications that are prescribed by licensed healthcare providers. The emphasis of Medicare Part D on prescription drug reimbursement distinguishes it clearly from these other healthcare services and supports, making it the correct answer in this context.
