Final answer:
Procedural RVU is not part of the Resource-Based Relative Value Scale (RBRVS) formula; rather, Practice Expense RVU, Work RVU, and Professional Liability RVU are the main components used to determine Medicare Fee Schedule reimbursements.
Step-by-step explanation:
The Medicare Fee Schedule is based on the Resource-Based Relative Value Scale (RBRVS), which incorporates several components to calculate reimbursements for medical services. The primary components are the Practice Expense Relative Value Unit (RVU), the Work RVU, and the Professional Liability Insurance RVU.
However, among the options given, Procedural RVU is not a component of the RBRVS formula. Instead, the Practice Expense RVU covers the costs associated with maintaining a practice, the Work RVU reflects the time and skill required for a physician to provide a service, and the Professional Liability RVU accounts for malpractice insurance expenses.
