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.
Anti-infectives
72.8%Nucleoside and nucleotide reverse transcriptase inhibitors72.8%Vemlidy63%Tenofovir Disoproxil Fumarate37%Part D<11 patientsMetabolism & gastrointestinal
27.2%Rifamycin Antibacterial13.6%Xifaxan100%Part D<11 patientsBile Acid13.6%Ursodiol100%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
