Medicaid work

$2,379 in 2021

Medicaid paid $2,379 for 26 billed services this clinician did in 2021, up to 12 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.
