Which of the following is not covered by Medicare Part B?

Medicare Part B is designed to cover outpatient services, including preventive care, doctor visits, and certain medical supplies. Among the coverage areas it includes are surgical services performed in an outpatient setting, diagnostic X-rays, and various medical supplies used in a doctor's office.

Inpatient rehabilitation, on the other hand, is primarily covered under Medicare Part A, which focuses on hospital insurance and inpatient care. This includes services provided to individuals who have been admitted to a hospital or a skilled nursing facility for rehabilitation services after a qualifying hospital stay. Therefore, inpatient rehabilitation does not fall under the Purview of Medicare Part B, making it the correct answer in this context.

Understanding the distinction between the coverage provided by Part A and Part B is essential for navigating Medicare services effectively.
