Medicaid work

$4,656 in 2024

Medicaid paid $4,656 for 32 billed services this clinician did in 2024, up to 15 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.

Pharmacies billed $1,862,542 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

153 generic and fewer than 11 brand-name prescriptions · $1,862,542 in drug cost · 15 antibiotic prescriptions.

Part D prescriptions only. The opioid rate is opioid prescriptions as a share of all this clinician's Part D prescriptions; surgeons and pain specialists run higher than others, so it is shown against the same specialty.
