Drugs they prescribed that Part D paid
$20,062
Pharmacies billed $20,062 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
210 generic and fewer than 11 brand-name prescriptions · $20,062 in drug cost · 11 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.
