Medicaid work

$6,740 in 2024

Medicaid paid $6,740 for 84 billed services this clinician did in 2024, up to 16 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

$25,647

Pharmacies billed $25,647 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 809) in 2024. At or below the middle of the specialty; the typical psychiatry clinician is at 0%.

786 generic and 23 brand-name prescriptions · $25,647 in drug cost · 64 antipsychotic prescriptions to people over 65.

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.
