What Part B can help cover
- Doctors’ and other health-care professional services
- Outpatient care and certain home health services
- Durable medical equipment
- Ambulance services when requirements are met
- Many preventive and screening services
Ask whether the provider accepts Medicare assignment and whether frequency, documentation, prior authorization, or medical-necessity rules apply.
