This variable indicates the total amount paid for part B tests by a primary payer other than Medicare 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 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.
