$5,293 in 2024
Medicaid paid $5,293 for 51 billed services this clinician did in 2024, up to 19 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.
