Medicaid work

$123,464 in 2024

Medicaid paid $123,464 for 618 billed services this clinician did in 2024, up to 30 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

$6,607

Pharmacies billed $6,607 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 87) in 2024. At or below the middle of the specialty; the typical ophthalmology clinician is at 0%.

67 generic and 20 brand-name prescriptions · $6,607 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.

Largest Part D drug costs
Prednisolone Acetate15$1,054$70
Latanoprost13$150$12
