Drugs they prescribed that Part D paid
$510

90 generic and 0 brand-name prescriptions · $510 in drug cost · 27 antibiotic prescriptions to 26 people.
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.
