Drugs they prescribed that Part D paid

$159,651

606 generic and fewer than 11 brand-name prescriptions · $159,651 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.
