Medicaid work
$2,375 in 2022
Medicaid paid $2,375 for 31 billed services this clinician did in 2022, up to 17 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.
