Emergency Department Visit With High Level of Medical Decision Making99285	29	$161
Emergency Department Visit With Low Level of Medical Decision Making99283	22	$65
Emergency Department Visit With Moderate Level of Medical Decision Making99284	20	$111

Typical Medicare-allowed amounts for these services range $65–$161 (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.

Open Payments discloses payments and transfers of value (meals, travel, consulting, research, royalties) from drug and device makers to providers. This is a transparency signal, not a verdict — such payments are legal and common, and their presence is neither an endorsement nor a criticism. Source: CMS Open Payments, program year 2024.
