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) |
|---|---|---|
| Established Patient Office Or Other Outpatient Visit With Moderate Level of Decision Making, If Using Time, 30 Minutes Or More99214 | 64 | $128 |
| New Patient Office Or Other Outpatient Visit With Moderate Level of Medical Decision Making, If Using Time, 45 Minutes Or More99204 | 36 | $167 |

| Detection Test By Immunoassay With Direct Visual Observation for Severe Acute Respiratory Syndrome Coronavirus 2 (covid-19)87811 | 19 | $41 |
| Automated Urinalysis Test81003 | 13 | $2 |
Typical Medicare-allowed amounts for these services range $2–$167 (2024). The Medicare-allowed amount is what Medicare recognizes for a service under fee-for-service — a reference figure for 2024, 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 |
|---|---|---|
| Methylprednisolone | 38 | 37 |
| Amoxicillin/Potassium Clavbrand: Amoxicillin-Clavulanate Potass | 33 | 32 |
| Prednisone | 29 | 28 |
| Cephalexin | 20 | 20 |
| Doxycycline Hyclate | 15 | 14 |
| Nirmatrelvir/Ritonavirbrand: Paxlovid | 15 | 15 |
| Azithromycin | 15 | 15 |
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.
