Medicaid paid $1,266 for 41 billed services this clinician did in 2021, up to 16 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.
