Medicare Part B covers services and supplies considered medically necessary to treat or diagnose a disease or condition, as well as preventative services to avert illness. Decisions about which procedures are covered by Medicare Part B are made by federal and state laws, Medicare, and local companies that process Medicare claims, according to Medicare.
Some of the types of services that Medicare Part B covers are doctor visits, lab tests and surgeries. Medicare Part B also covers durable medical equipment such as blood sugar monitors, infusion pumps, and supplies to administer certain drugs, walkers, wheelchairs and hospital beds, as stated by Medicare. Only medically necessary equipment for use in the home, prescribed by a doctor, is covered. In addition, the medical equipment prescribed must be considered long-lasting.
Medicare Part B also covers services, such as participation in clinical research, ambulances in emergencies, getting second opinions before surgery and mental health treatment. Mental health treatment is covered for inpatient or outpatient services, as well as for partial hospitalization, as explained by Medicare. Most preventative services are covered at no cost to you, if you get these services from a provider that accepts assignment. Assignment means that the health care provider is paid directly by Medicare for the service.
