Medicaid work

$5,321 in 2024

Medicaid paid $5,321 for 423 billed services this clinician did in 2024, up to 27 people in a month for one service.

Medicaid and CHIP claims where this clinician did the service, fee-for-service and managed care together. Any month with fewer than 11 patients is hidden, so small Medicaid practices undercount.
