What is the coinsurance rate for physicians' services covered under Medicare Part B?

The coinsurance rate for physicians' services under Medicare Part B is 20 percent. This means that once a beneficiary has met their annual deductible for Part B services, they are responsible for paying 20 percent of the Medicare-approved amount for most outpatient services, including doctor visits, diagnostic tests, and preventive services. Medicare pays the remaining 80 percent.

This coinsurance structure is designed to share costs between the Medicare program and beneficiaries, encouraging patients to be conscious of their healthcare utilization while also providing substantial coverage from Medicare. The 20 percent coinsurance is applicable after deductibles are met and is a standard feature of Medicare Part B, reinforcing the program's objective to make necessary medical services affordable while providing beneficiaries with necessary coverage.
