Medicaid work

$13,532 in 2023

Medicaid paid $13,532 for 238 billed services this clinician did in 2023, 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.
