Medicare volume is ranked against active providers in the same specialty.

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	84	$168
Emergency Department Visit With Moderate Level of Medical Decision Making99284	55	$117
Critical Care, First 30-74 Minutes99291	40	$208
Ultrasound of Heart, Follow-Up93308	18	$24
Emergency Department Visit With Low Level of Medical Decision Making99283	17	$69

Typical Medicare-allowed amounts for these services range $24–$208 (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.
