Medicaid work
$2,294 in 2023
Medicaid paid $2,294 for 38 billed services this clinician did in 2023, up to 14 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.
