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	112	$160
Emergency Department Visit With Moderate Level of Medical Decision Making99284	66	$111
Routine Electrocardiogram (ecg) Using at Least 12 Leads With Interpretation and Report Only93010	49	$8
Critical Care, First 30-74 Minutes99291	14	$196

Typical Medicare-allowed amounts for these services range $8–$196 (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.
