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 of Polyps Or Growths of Large Bowel Using an Endoscope With Mechanical Snare45385 | 35 | $241 |
| Colorectal Cancer Screening; Colonoscopy on Individual at High RiskG0105 | 15 | $175 |
| Colorectal Cancer Screening; Colonoscopy on Individual Not Meeting Criteria for High RiskG0121 | 11 | $167 |
Typical Medicare-allowed amounts for these services range $167–$241 (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 |
|---|---|---|
| Famotidine | 76 | 36 |
| Omeprazole | 62 | 32 |
| Pantoprazole Sodium | 37 | 16 |
| Dicyclomine Hcl | 22 | 13 |
| Colestipol Hcl | 13 | — |
| Lipase/Protease/Amylasebrand: Creon | 12 | — |
| Ustekinumabbrand: Stelara | 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.
