Medicaid work

$7,520 in 2024

Medicaid paid $7,520 for 473 billed services this clinician did in 2024, up to 82 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

$129,950

Pharmacies billed $129,950 in 2024.

Opioids were 0% of their Part D prescriptions (0 of 766) in 2024. At or below the middle of the specialty; the typical cardiology clinician is at 0%.

633 generic and 133 brand-name prescriptions · $129,950 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.
