ResDAC is currently experiencing a high volume of requests, which may delay response and processing times. We are working to address the backlog as quickly as possible and appreciate your patience.
This variable is contained in the following files:
SAS Name
PTD_EVENTS
This variable is the count of events for Part D drugs for a given year (i.e., a unique count of the PDE_IDs). An event is a dispensed (filled) drug prescription that appears in the Prescription Drug Event (PDE) file.
Null/missing or 1-XXXX
The value will be null if the beneficiary was not enrolled in Part D or did not use any Part D drugs during the year.
PDEs consist of highly variable days supply of the medication. We also create a derived variable that counts a standard 30 day supply of a filled Part D prescription (see PTD_FILL_CNT).
