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 | 24 | $114 |
| Emergency Department Visit With High Level of Medical Decision Making99285 | 16 | $165 |
| Routine Electrocardiogram (ecg) Using at Least 12 Leads With Interpretation and Report Only93010 | 14 | $8 |
| Emergency Department Visit With Low Level of Medical Decision Making99283 | 13 | $67 |
Typical Medicare-allowed amounts for these services range $8–$165 (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) |
|---|---|
| Allopurinol | 20 |
| Albuterol Sulfatebrand: Albuterol Sulfate Hfa | 14 |
| Tiotropium Bromidebrand: Spiriva Respimat | 13 |
| Simvastatin | 12 |
| Amlodipine Besylate | 11 |
| Hydrocodone/Acetaminophenbrand: Hydrocodone-Acetaminophen | 11 |
| Lisinopril | 11 |
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.
