What is the basic cost-sharing structure of Medicare Part B?

The basic cost-sharing structure of Medicare Part B involves the patient being responsible for 20% of the Medicare-approved amount for most services, while Medicare covers the remaining 80%. This percentage applies after the patient has met their annual deductible. The 20% coinsurance is a significant aspect of Part B, which includes various outpatient services such as doctor visits, laboratory tests, and preventive screenings.

Understanding this structure is essential for patients enrolled in Medicare, as it affects their potential out-of-pocket costs. Medicare Part B does not require a flat fee or cover 100% of costs, and the patient does not pay 50% of all costs, highlighting the importance of recognizing the specific cost-sharing percentages that govern this program.
