Which part of Medicare primarily covers outpatient care?

Medicare Part B is primarily designed to cover outpatient care, which includes a range of services such as physician visits, diagnostic tests, preventive services, and various outpatient therapies. This part of Medicare is crucial for patients who require medical treatment without being admitted to a hospital. It emphasizes the management of patients' health through preventive measures and ongoing treatment, facilitating easier access to medical care as needed.

Part A is primarily focused on inpatient hospital services, covering stays in hospitals, skilled nursing facilities, hospice, and some home health care. Part C, also known as Medicare Advantage, encompasses both Part A and Part B benefits and potentially offers additional coverage through private insurers, but is not exclusively focused on outpatient care. Finally, Part D is specifically for prescription drug coverage, concentrating on the medications that beneficiaries may need rather than outpatient medical services. Hence, Part B stands out as the correct answer, reflecting its dedicated focus on outpatient care.
