Medicaid work

$4,303 in 2024

Medicaid paid $4,303 for 59 billed services this clinician did in 2024, up to 18 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

$508,396

Pharmacies billed $508,396 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 1,560) in 2024. At or below the middle of the specialty; the typical gastroenterology clinician is at 0%.

966 generic and fewer than 11 brand-name prescriptions · $508,396 in drug cost · 36 antibiotic prescriptions to 29 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.
