Medicaid paid $2,798 for 146 billed services this clinician did in 2024, up to 20 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.
