This variable indicates the total amount paid for Part B drugs by a primary payer other than Medicare for a given year. Part B drug claims are a subset of the claims in the Part B Carrier and DME data files.

The Part B drug claims are identified by BETOS codes (CCW variable BETOS_CD with values of 'D1G','O1D','O1E','O1G','I1E', or 'I1F'). Total Part B drug payments from a Primary Payer are calculated as the sum of the LINE_BENE_PRMRY_PYR_PD_AMT.
