Drugs they prescribed that Part D paid

$9,569

Pharmacies billed $9,569 in 2024.

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

147 generic and 13 brand-name prescriptions · $9,569 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.
