Signals a provider has no public data for (e.g. Medicare claims) are left out of the score entirely — never counted as zero — so providers without that data are not penalized. See the full formula and weights in our methodology.
What this provider prescribes (Medicare Part D)
Top drugs by Medicare Part D claim volume, 2024 · 10 distinct drugs on file.
| Drug | Part D claims (2024) |
|---|---|
| Haloperidol Decanoate | 17 |
| Aripiprazole | 15 |
| Benztropine Mesylate | 15 |
| Clozapine | 15 |
| Divalproex Sodium | 15 |
| Lithium Carbonate | 15 |
| Paliperidone Palmitatebrand: Invega Sustenna | 12 |
| Trazodone Hcl | 12 |
| Fluphenazine Hcl | 11 |
| Haloperidol | 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.
