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) |
|---|---|---|
| Removal and Microscopic Exam of Growth of Head, Neck, Hands, Feet, Or Genitals, 1-5 Tissue Blocks17311 | 92 | $694 |
| Removal and Microscopic Exam of Growth of Head, Neck, Hands, Feet, Or Genitals, Each Additional Stage, 1-5 Tissue Blocks17312 | 59 | $434 |
| Intermediate Repair of Wound of Face, Ears, Eyelids, Nose, Lips, Or Mouth, 2.6-5.0 Cm12052 | 22 | $175 |
Typical Medicare-allowed amounts for these services range $175–$694 (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 · 2 distinct drugs on file.
| Drug | Part D claims (2024) | Beneficiaries |
|---|---|---|
| Mupirocin | 155 | 137 |
| Cephalexin | 22 | 21 |
Medicare Part D only. These counts cover prescriptions paid through Medicare Part D in 2024 — they do notinclude 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 no Part D record, 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.
