Medicaid work
$609 in 2023
Medicaid paid $609 for 13 billed services this clinician did in 2023, up to 13 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
$71,733
Pharmacies billed $71,733 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 624) in 2024. At or below the middle of the specialty; the typical dermatology clinician is at 0%.
590 generic and 34 brand-name prescriptions · $71,733 in drug cost · 26 antibiotic prescriptions to 15 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.
