Drugs they prescribed that Part D paid
$892
Pharmacies billed $892 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
68 generic and 13 brand-name prescriptions · $892 in drug cost · 14 antibiotic prescriptions to 11 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.
