Drugs they prescribed that Part D paid
$9,129
Pharmacies billed $9,129 in 2024.

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.
