Medicaid work

$3,000 in 2024

Medicaid paid $3,000 for 346 billed services this clinician did in 2024, up to 21 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

Pharmacies billed $2,689 in 2024.

82 generic and fewer than 11 brand-name prescriptions · $2,689 in drug cost · 43 antibiotic prescriptions to 11 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.
