Part B Physician Events

This variable is the count of events in the part B physician office services (PHYS) for a given year. An event is defined as each line item that contains the relevant service.

Physician office claims are a subset of the claims in the Part B Carrier and DME data files, and a subset of physician evaluation and management claims (note that E&M are tabulated separately in this data file). The PHYS claims are defined as those with a line BETOS code (BETOS_CD) where the first three digits =M1A or M1B (the remainder of physician services which occur in different settings appear in EM_MDCR_PMT).
