Ambulatory Surgery Center Medicare Payments

SAS Name

This variable is the total Medicare payments in the part B ambulatory surgery center (ASC) setting 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 Medicare Payments are calculated as the sum of LINE_NCH_PMT_AMT where the LINE_PRCSG_IND_CD was ('A','R', or 'S').


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.
