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) |
|---|---|---|
| Dialysis Services, 2-3 Physician Visits Per Month (20 Years Or Older)90961 | 30 | $237 |
| Dialysis Services, 1 Physician Visit Per Month (20 Years Or Older)90962 | 21 | $162 |
| Dialysis Services, 4 Or More Physician Visits Per Month (20 Years Or Older)90960 | 17 | $268 |
Typical Medicare-allowed amounts for these services range $162–$268 (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 · 8 distinct drugs on file.
| Drug | Part D claims (2024) |
|---|---|
| Clonidine Hcl | 19 |
| Sevelamer Carbonate | 19 |
| Nifedipinebrand: Nifedipine Er | 15 |
| Amlodipine Besylate | 13 |

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 , 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.
