Restructured BETOS Classification System

Published by Office of Enterprise Data and Analytics (OEDA) | U.S. Department of Health & Human Services | Catalog Last Checked: September 28, 2026 at 08:31 PM
The Restructured BETOS Classification System (RBCS) dataset is a taxonomy that allows researchers to group healthcare service codes for Medicare Part B services (i.e., HCPCS codes) into clinically meaningful categories and subcategories. It is based on the original Berenson-Eggers Type of Service (BETOS) classification created in the 1980s, and includes notable updates such as Part B non-physician services. The RBCS will undergo annual updates by a technical expert panel of researchers and clinicians.
