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	107	$168
Emergency Department Visit With Moderate Level of Medical Decision Making99284	68	$115
Routine Electrocardiogram (ecg) Using at Least 12 Leads With Interpretation and Report Only93010	31	$8
Emergency Department Visit With Low Level of Medical Decision Making99283	14	$67
Critical Care, First 30-74 Minutes99291	11	$203

Typical Medicare-allowed amounts for these services range $8–$203 (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
Methylprednisolone	17	17
Sulfamethoxazole/Trimethoprimbrand: Sulfamethoxazole-Trimethoprim	15	15
Ondansetronbrand: Ondansetron Odt	13	13
Cephalexin	13	13

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.
