Medicaid work

$829 in 2020

Medicaid paid $829 for 27 billed services this clinician did in 2020, up to 14 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

$111,356

Pharmacies billed $111,356 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 867) in 2024. At or below the middle of the specialty; the typical ophthalmology clinician is at 0%.

478 generic and 389 brand-name prescriptions · $111,356 in drug cost.

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.
