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) |
|---|---|---|
| Amplifed Dna Or Rna Probe Detection of Severe Acute Respiratory Syndrome Coronavirus 2 (covid-19) Antigen87635 | 38 | $49 |
| Automated Urinalysis Test81003 | 30 | $2 |
| Detection Test By Nucleic Acid for Strep (streptococcus, Group A), Amplified Probe Technique87651 | 25 | $34 |
| Detection Test By Nucleic Acid for Multiple Types Influenza Virus87502 | 20 | $94 |
Typical Medicare-allowed amounts for these services range $2–$94 (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 | 27 | 27 |
| Doxycycline Monohydrate | 27 | 27 |

| Fluconazole | 11 | 11 |
Medicare Part D only. 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.
