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 Low Level OD Decision Making, If Using Time, 20 Minutes Or More99213 | 191 | $95 |
| Removal of Noncancer Thickened Skin Growth, 2-4 Growths11056 | 91 | $87 |

| X-Ray of Foot, Minimum of 3 Views73630 | 36 | $36 |
Typical Medicare-allowed amounts for these services range $36–$117 (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 |
|---|---|---|
| Ciclopirox Olaminebrand: Ciclopirox | 24 | 19 |
| Gabapentin | 24 | — |
| Amoxicillin/Potassium Clavbrand: Amoxicillin-Clavulanate Potass | 23 | 15 |
| Ammonium Lactate | 17 | 13 |
| Ciclopirox | 15 | — |
| Econazole Nitrate | 12 | — |
| Meloxicam | 11 | 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.
