Drugs they prescribed that Part D paid

$9,722

Pharmacies billed $9,722 in 2024.

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

Opioids were 0% of their Part D prescriptions (0 of 196) in 2024. At or below the middle of the specialty; the typical general surgery clinician is at 34%.

186 generic and fewer than 11 brand-name prescriptions · $9,722 in drug cost · 52 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.
