Medicare prescribing footprint (2022)
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.

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.

A basic profile from our physician directory: identity and practice contact from the federal NPPES registry, research from OpenAlex, trials from ClinicalTrials.gov, payments from CMS Open Payments — shown itemized where we have matched records, as a count where we only have a total. This person hasn't been through our full identity-adjudication pipeline yet, so funding, congress activity and public presence aren't shown. Absence of a section means “not yet looked,” never “none found.”
