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) |
|---|---|---|
| Hospital Discharge Day Management, 30 Minutes Or Less99238 | 20 | $67 |
| Emergency Department Visit With Moderate Level of Medical Decision Making99284 | 17 | $94 |
| Hospital Discharge Day Management, More Than 30 Minutes99239 | 15 | $95 |
| Emergency Department Visit With High Level of Medical Decision Making99285 | 12 | $136 |
Typical Medicare-allowed amounts for these services range $67–$136 (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 · 4 distinct drugs on file.
| Drug | Part D claims (2024) | Beneficiaries |
|---|---|---|
| Oxycodone Hcl | 22 | 22 |
| Levothyroxine Sodium | 12 | — |
| Bupropion Hclbrand: Bupropion Xl | 12 | — |
| Citalopram Hydrobromidebrand: Citalopram Hbr | 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 no Part D record, 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.
