Medicaid work

$4,234,329 in 2024

Medicaid paid $4,234,329 for 66,518 billed services this clinician did in 2024, up to 869 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

$3,230

Pharmacies billed $3,230 in 2024.

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

67 generic and fewer than 11 brand-name prescriptions · $3,230 in drug cost · 17 antibiotic prescriptions to 12 people.

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.
