Drugs they prescribed that Part D paid

$187,023

Pharmacies billed $187,023 in 2024.

Opioids were 0% of their Part D prescriptions (0 of 766) in 2024. At or below the middle of the specialty; the typical gastroenterology clinician is at 0%.

556 generic and 210 brand-name prescriptions · $187,023 in drug cost.

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.
