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) |
|---|---|---|
| Emergency Department Visit With Moderate Level of Medical Decision Making99284 | 116 | $96 |
| Emergency Department Visit With High Level of Medical Decision Making99285 | 36 | $138 |
| Emergency Department Visit With Low Level of Medical Decision Making99283 | 31 | $57 |
| Critical Care, First 30-74 Minutes99291 | 11 | $170 |
Typical Medicare-allowed amounts for these services range $57–$170 (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 |
|---|---|---|
| Cephalexin | 32 | 32 |
| Ondansetronbrand: Ondansetron Odt | 31 | 31 |
| Oxycodone Hcl/Acetaminophenbrand: Oxycodone-Acetaminophen | 24 | 24 |
| Doxycycline Hyclate | 16 | 16 |
| Amoxicillin/Potassium Clavbrand: Amoxicillin-Clavulanate Potass | 14 | 14 |
| Hydrocodone/Acetaminophenbrand: Hydrocodone-Acetaminophen | 14 | 14 |
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.
