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.
Nervous system
61.2%Benzodiazepine35.3%Alprazolam100%Part D≥41 patientsOpioid Agonist25.9%Tramadol Hcl100%Part D≥34 patientsMetabolism & gastrointestinal
38.8%Serotonin-3 Receptor Antagonist38.8%Ondansetron Odt100%Part D≥33 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.
