Medicaid work

$223 in 2024

Medicaid paid $223 for 31 billed services this clinician did in 2024, 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

$38,782

Pharmacies billed $38,782 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

Opioids were 7% of their Part D prescriptions (25 of 359) in 2024. A higher opioid share than 9 in 10 peers; the typical obstetrics & gynecology clinician is at 0%.

275 generic and fewer than 11 brand-name prescriptions · $38,782 in drug cost · 17 antibiotic prescriptions to 14 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.
