Medicaid work

Medicaid paid $3,908 for 45 billed services this clinician did in 2024, up to 19 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

$182,013

Pharmacies billed $182,013 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 1,171) in 2024. At or below the middle of the specialty; the typical dermatology clinician is at 0%.

1,113 generic and 58 brand-name prescriptions · $182,013 in drug cost · 40 antibiotic prescriptions to 32 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.
