Part D Prescriber Characteristics File

The Medicare Part D Prescriber Characteristics file contains descriptive information for the prescriber identified on a Part D Event file record.

What does this file include? (variable highlights)

Why do researchers request this file?

  • Studies describing prescribing patterns based on prescriber specialty
  • Evaluation of clinical outcome based on prescriber characteristics

Special considerations

  • Prior to CY2014 data, the prescriber ID is the encrypted CCW Prescriber ID, which cannot be linked to external, non-CMS Part D data sources.
