Drugs they prescribed that Part D paid
$18,671

146 generic and 26 brand-name prescriptions · $18,671 in drug cost · 14 antibiotic prescriptions.
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.
