Berenson-Eggers Type of Service (BETOS) codes are assigned for each Health Care Financing Administration Common Procedure Coding System (HCPCS) procedure code.
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 overtime; and is relatively immune to minor changes in technology or practice patterns.
