Ambulatory Surgery Center Primary Payer Amount

SAS Name

This variable indicates the total amount paid for services in the ambulatory surgery center (ASC) setting by a primary payer other than Medicare for a given year. ASC claims are a subset of the claims in the Part B Carrier data file.

The ASC claims are identified by the claim lines where the LINE_CMS_TYPE_SRVC_CD = 'F'. The total ASC Primary Payer Payments are calculated as the sum of the LINE_BENE_PRMRY_PYR_PD_AMT.


There are 11 cost/use categories from the Carrier Part B and DME data files – the ASC, Anesthesia, Part B Drug, Physician, E & M, dialysis, imaging, tests, other procedures, DME and other carrier claims.
