Drugs they prescribed that Part D paid

$2,146

Pharmacies billed $2,146 in 2024.

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

Opioids were 73% of their Part D prescriptions (143 of 197) in 2024. A higher opioid share than 9 in 10 peers; the typical orthopedic surgery clinician is at 31%.

197 generic and 0 brand-name prescriptions · $2,146 in drug cost · 23 antibiotic prescriptions to 16 people.

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.
