Medicaid work
$23,244 in 2024
Medicaid paid $23,244 for 583 billed services this clinician did in 2024, up to 28 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
$111,586
Pharmacies billed $111,586 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 550) in 2024. At or below the middle of the specialty; the typical gastroenterology clinician is at 0%.
423 generic and 127 brand-name prescriptions · $111,586 in drug cost · 27 antibiotic prescriptions to 16 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.
