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 High Level of Medical Decision Making99285	127	$151
Emergency Department Visit With Moderate Level of Medical Decision Making99284	105	$104
Critical Care, First 30-74 Minutes99291	14	$183
Emergency Department Visit With Low Level of Medical Decision Making99283	11	$61

Typical Medicare-allowed amounts for these services range $61–$183 (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)	Beneficiaries
Oxycodone Hcl	37	37
Naproxen	29	29
Doxycycline Hyclate	24	24
Ondansetronbrand: Ondansetron Odt	19	19
Cefdinir	17	17
Amoxicillin/Potassium Clavbrand: Amoxicillin-Clavulanate Potass	11	11
Prednisone	11	11

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.
