Medicaid work

$30,711 in 2024

Medicaid paid $30,711 for 301 billed services this clinician did in 2024, up to 16 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.
