This variable is contained in the following files:
SAS Name
FORMULARY_ID
This variable is the unique identification number assigned to each formulary. Part D plans submit their formularies to CMS and identify the drug products that are covered using the National Library of Medicine’s RxNorm Concept Unique Identifiers (RXCUIs).
The same formulary may be used by more than one plan benefit package (PBP) within a contract.
Values: 8-digit numeric value
Researchers interested in linking the Utilization Management (UM) variables (tier, step therapy, quantity limits, and prior authorization) to the PDE data will need to link the FORMULARY_ID and FRMLRY_RX_ID to the Formulary Characteristics file to get the UM variables. The CCW constructs a Formulary Characteristics file from the CMS Approved Formulary Data found in the CMS’s Health Plan Management System (HPMS). This variable is first available in 2010. This variable was always encrypted from 2010–2012 to comply with CMS privacy rules.
