What this provider prescribes (Medicare Part D)
Top drugs by Medicare Part D claim volume, 2024 · 7 distinct drugs on file.
| Drug | Part D claims (2024) | Beneficiaries |
|---|---|---|
| Ketoconazole | 31 | 14 |
| Clobetasol Propionate | 18 | 12 |
| Doxycycline Monohydrate | 15 | — |
| Triamcinolone Acetonide | 15 | 14 |
| Ciclopirox Olaminebrand: Ciclopirox | 13 | — |
| Etanerceptbrand: Enbrel Sureclick | 11 | — |
| Nystatin | 11 | — |
These counts cover prescriptions paid through Medicare Part D in 2024 — they include cash-pay, commercial-insurance, Medicaid, or Part B–administered drugs, and badly undercount high cash-pay categories (e.g. GLP-1 weight-loss, testosterone, and ED medications). Any drug with 10 or fewer claims is omitted by CMS, and beneficiary counts under 11 are suppressed — so a missing drug means , never zero. This is a factual claims summary, not an endorsement, not medical advice, and not a consumer report. Source: CMS Medicare Part D Prescribers — by Provider and Drug.
