Medicaid work

$1,044 in 2023

Medicaid paid $1,044 for 27 billed services this clinician did in 2023, up to 13 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.

Drugs they prescribed that Part D paid

$752

Pharmacies billed $752 in 2024.

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

28 generic and 0 brand-name prescriptions · $752 in drug cost.

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.
