Drugs they prescribed that Part D paid

$6,323

Pharmacies billed $6,323 in 2024.

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

Opioids were 31% of their Part D prescriptions (73 of 236) in 2024. At or below the middle of the specialty; the typical orthopedic surgery clinician is at 31%.

230 generic and fewer than 11 brand-name prescriptions · $6,323 in drug cost · 12 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.
