Berenson-Eggers Type of Service (BETOS) Codes

CMS has restructured the BETOS classification system effective 2023.

The rest of this page shows pre-2023 data.

The BETOS coding system was developed primarily for analyzing the growth in Medicare expenditures. The coding system covers all HCPCS codes; assigns a HCPCS code to only one BETOS code; consists of readily understood clinical categories (as opposed to statistical or financial categories); consists of categories that permit objective assignment; is stable over time; and is relatively immune to minor changes in technology or practice patterns.
