What this provider does (Medicare)
Based on Medicare fee-for-service claims, 2024; not all care is captured.

| Physician Or Allowed Practitioner Certification for Medicare-Covered Home Health Services Under a Home Health Plan of Care (patient Not Present), Including Contacts With Home Health Agency and Review of Reports of Patient Status Required By Physicians andG0180 | 14 | $42 |
Typical Medicare-allowed amounts for these services range $42–$93 (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 · 6 distinct drugs on file.
| Drug | Part D claims (2024) | Beneficiaries |
|---|---|---|
| Gabapentin | 18 | 18 |
| Atorvastatin Calcium | 16 | 13 |
| Oxycodone Hcl | 16 | 16 |
| Pantoprazole Sodium | 14 | 12 |
| Prednisone | 14 | — |
| Hydrocodone/Acetaminophenbrand: Hydrocodone-Acetaminophen | 12 | 12 |
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.
