Medicaid work
$12,016 in 2023
Medicaid paid $12,016 for 1,447 billed services this clinician did in 2023, up to 29 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.
