Medicaid work

Medicaid paid $120,857 for 1,772 billed services this clinician did in 2019, up to 111 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

$1,423

Pharmacies billed $1,423 in 2024.

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

94 generic and fewer than 11 brand-name prescriptions · $1,423 in drug cost · 40 antibiotic prescriptions to 38 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.
