Medicaid work

$425 in 2021

Medicaid paid $425 for 12 billed services this clinician did in 2021, up to 12 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

$880,694

Pharmacies billed $880,694 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 1,974) in 2024. At or below the middle of the specialty; the typical gastroenterology clinician is at 0%.

1,478 generic and 496 brand-name prescriptions · $880,694 in drug cost · 160 antibiotic prescriptions to 75 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.
