Drugs they prescribed that Part D paid

$613,560

Pharmacies billed $613,560 in 2024.

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

315 generic and 786 brand-name prescriptions · $613,560 in drug cost · 42 antibiotic prescriptions to 25 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.
