Which prospective payment system determines payment for physician services covered under Medicare Part B?

The correct answer is the system that determines payment for physician services covered under Medicare Part B is referred to as the Resource-Based Relative Value Scale (RBRVS).

RBRVS is a payment system that calculates reimbursements based on the resources required to provide services. It assigns values to various medical services and procedures, considering factors such as the time, skill, and intensity of the service provided. This system helps ensure that payments to healthcare providers are commensurate with the complexity and demands of the services they deliver.

This method allows for a more standardized approach, which is vital for maintaining equity in reimbursement across different types of healthcare providers and maintaining a sustainable framework for Medicare expenses. The system has helped streamline the payment process for physician services and enhances the overall efficiency of Medicare Part B.

For example, MS-DRGs are used for inpatient hospital services, APCs are utilized for outpatient hospital services, and ASCs relate to surgical centers. Understanding the distinctions between these systems is crucial for anyone involved in healthcare reimbursement practices.
