Medicaid work

$10,283 in 2024

Medicaid paid $10,283 for 298 billed services this clinician did in 2024, up to 29 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

$2,658

Pharmacies billed $2,658 in 2024.

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

Opioids were 5% of their Part D prescriptions (11 of 219) in 2024. At or below the middle of the specialty; the typical emergency medicine clinician is at 12%.

196 generic and fewer than 11 brand-name prescriptions · $2,658 in drug cost · 81 antibiotic prescriptions to 74 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.
