Medicaid work

$4,296 in 2024

Medicaid paid $4,296 for 55 billed services this clinician did in 2024, up to 17 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

$4,849

Pharmacies billed $4,849 in 2024.

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

Opioids were 0% of their Part D prescriptions (0 of 201) in 2024. At or below the middle of the specialty; the typical emergency medicine clinician is at 12%.

175 generic and 26 brand-name prescriptions · $4,849 in drug cost · 91 antibiotic prescriptions to 84 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.
