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
93.8%Aromatase Inhibitor65%Anastrozole56%Letrozole26%Exemestane18%Part D≥46 patientsKinase inhibitor13.7%Verzenio55%Ibrance45%Part D<11 patientsNervous system
6.2%Phenothiazine6.2%Prochlorperazine Maleate100%Part D≥13 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.
