Drugs they prescribed that Part D paid

$307,441

Pharmacies billed $307,441 in 2024.

181 generic and 92 brand-name prescriptions · $307,441 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.
