Medicaid work

$437,727 in 2024

Medicaid paid $437,727 for 10,169 billed services this clinician did in 2024, up to 228 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

$1,979

Pharmacies billed $1,979 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 271) in 2024. At or below the middle of the specialty; the typical dentist clinician is at 0%.

270 generic and fewer than 11 brand-name prescriptions · $1,979 in drug cost · 160 antibiotic prescriptions to 113 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.
