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

    55.9%
    N-methyl-D-aspartate Receptor Antagonist36.8%
    Memantine Hcl100%
    Part D<11 patients
    Other antiepileptics19.1%
    Levetiracetam100%
    Part D<11 patients

  • Blood & clotting

    Factor Xa inhibitor22.1%
    Eliquis100%

  • Anti-infectives

    Tetracycline-class Drug22.1%
    Minocycline Hcl100%
    Part D<11 patients
Where care is delivered (Part B)22.4% facility · 77.6% office

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.
