Which service is covered under Medicare Part B?

Medicare Part B primarily covers outpatient services, which include necessary medical services provided by healthcare professionals. General practitioner visits fall under this category as they are considered outpatient care, ensuring that patients have access to essential healthcare providers for routine check-ups, preventive services, and treatment of medical conditions outside of a hospital setting.

Hospital stays are covered under Medicare Part A, which focuses on inpatient services. Long-term care is generally not covered by either Part A or Part B of Medicare, as it typically refers to non-medical personal care or custodial care required over an extended period. Prescription drug plans are provided under Medicare Part D, designed specifically to assist with the costs of outpatient prescription medications. Thus, the correct choice accurately reflects the services covered by Medicare Part B.
