This variable is the total Medicare payments for part B tests for a given year. Claims for tests are a subset of the claims in the Part B Carrier data file.
These claims are defined as those with a line BETOS code (BETOS_CD) where the first digit =T. The total Medicare payments are calculated as the sum of LINE_NCH_PMT_AMT where the LINE_PRCSG_IND_CD was ('A','R', or 'S') - for all relevant lines.
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.
