Medicare prescribing footprint (2024)

The drugs this prescriber writes for Medicare patients, grouped by drug class and therapeutic area. Every percentage is a share of their total prescribing, so you can see what they prescribe most. These are proportions, not patient counts or dollar amounts. No condition is inferred: the claims record what was prescribed, never why.

  • Cancer & immunology

    50%
    Anti-androgens50%
    Nubeqa100%
    Part D<11 patients
  • Metabolism & gastrointestinal

    50%
    Corticosteroid50%
    Prednisone100%
    Part D≥11 patients
Where care is delivered (Part B)0% facility · 100% office

Drug classes come from the WHO ATC and U.S. National Library of Medicine (RxClass) classifications; prescribing counts come from the CMS Medicare Part D Prescribers file. Each drug is counted once, under its primary class. Medicare fee-for-service only, so no Medicare Advantage, commercial, or pediatric prescribing is included. CMS publishes this data about 17 months after the fact.

1 NIH research award on record, funded 2021–2022 per NIH RePORTER. The latest:
