Drugs they prescribed that Part D paid

$5,032

Pharmacies billed $5,032 in 2024.

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

38 generic and fewer than 11 brand-name prescriptions · $5,032 in drug cost.

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.
