Medicaid work

$56,314 in 2024

Medicaid paid $56,314 for 3,442 billed services this clinician did in 2024, up to 86 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.
