Medicaid paid $42,932 for 1,080 billed services this clinician did in 2024, up to 53 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

$11,850

Pharmacies billed $11,850 in 2024.

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

Opioids were 10% of their Part D prescriptions (23 of 242) in 2024. At or below the middle of the specialty; the typical emergency medicine clinician is at 12%.

219 generic and 23 brand-name prescriptions · $11,850 in drug cost · 84 antibiotic prescriptions to 70 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.
