Drugs they prescribed that Part D paid
$48,349
Pharmacies billed $48,349 in 2024.

Opioids were 0% of their Part D prescriptions (0 of 243) in 2024. At or below the middle of the specialty; the typical obstetrics & gynecology clinician is at 0%.
156 generic and 87 brand-name prescriptions · $48,349 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.
