Medicaid work
$1,659 in 2022
Medicaid paid $1,659 for 81 billed services this clinician did in 2022, up to 21 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
$157,871
Pharmacies billed $157,871 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 1,501) in 2024. At or below the middle of the specialty; the typical ophthalmology clinician is at 0%.
873 generic and 628 brand-name prescriptions · $157,871 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.
