Drugs they prescribed that Part D paid

$5,314,946

Pharmacies billed $5,314,946 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

878 generic and 332 brand-name prescriptions · $5,314,946 in drug cost · 24 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.
