Medicare volume is ranked against active providers in the same specialty. 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.

What this provider does (Medicare)
Based on Medicare fee-for-service claims, 2024; not all care is captured.
| Service (HCPCS) | Medicare services | Typical Medicare-allowed (2024) |
|---|---|---|
| Administration of Vaccine, Each Additional Vaccine90472 | 41 | $13 |
| Administration of Hepatitis B VaccineG0010 | 21 | $34 |
| Administration of Pneumococcal VaccineG0009 | 16 | $34 |
Typical Medicare-allowed amounts for these services range $13–$34 (2024). The Medicare-allowed amount is what Medicare recognizes for a service under fee-for-service — a reference figure for 2024, not a price quote and not what you would be billed. Medicare Part B covers roughly an eighth of all NPIs (65+ skew); services with fewer than 11 beneficiaries are suppressed by CMS.

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 |
|---|---|---|
| Azithromycin | 306 | 304 |
| Atovaquone/Proguanil Hclbrand: Atovaquone-Proguanil Hcl | 224 | 216 |
| Doxycycline Hyclate | 30 | 27 |

| Acetazolamide | 22 | 22 |
| Isoniazid | 17 | — |
| Typhoid Vi Polysacch Vaccinebrand: Typhim Vi | 14 | 14 |
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.
