Drugs they prescribed that Part D paid

$6,803

Pharmacies billed $6,803 in 2024.

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

63 generic and fewer than 11 brand-name prescriptions · $6,803 in drug cost · 13 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.
