Drugs they prescribed that Part D paid

$1,408

Pharmacies billed $1,408 in 2024.

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

Opioids were 55% of their Part D prescriptions (55 of 101) in 2024. A higher opioid share than 9 in 10 peers; the typical physician assistant clinician is at 1%.

100 generic and fewer than 11 brand-name prescriptions · $1,408 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.

Largest Part D drug costs
Oxycodone44$197$4
Celecoxib12$184$15
