Medicaid work

$262,360 in 2023

Medicaid paid $262,360 for 2,674 billed services this clinician did in 2023, up to 54 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.
