Medicaid work

$26,002 in 2024

Medicaid paid $26,002 for 923 billed services this clinician did in 2024, up to 98 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

$24,705

Pharmacies billed $24,705 in 2024.

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

Opioids were 0% of their Part D prescriptions (0 of 69) in 2024. At or below the middle of the specialty; the typical adult congenital heart disease clinician is at 0%.

45 generic and fewer than 11 brand-name prescriptions · $24,705 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.
