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 patientsMetabolism & gastrointestinal
50%Corticosteroid50%Prednisone100%Part D≥11 patients
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.
NIH funding
Updated 27 Aug 2026
1 NIH research award on record, funded 2021–2022 per NIH RePORTER. The latest:
