Drugs they prescribed that Part D paid

$6,390

Pharmacies billed $6,390 in 2024.

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

Opioids were 2% of their Part D prescriptions (13 of 760) in 2024. A higher opioid share than 9 in 10 peers; the typical dermatology clinician is at 0%.

760 generic and 0 brand-name prescriptions · $6,390 in drug cost · 259 antibiotic prescriptions to 221 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.
