Medicaid work
$742 in 2024
Medicaid paid $742 for 1,673 billed services this clinician did in 2024, up to 218 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.
