Drugs they prescribed that Part D paid
$6,564
Pharmacies billed $6,564 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 42% of their Part D prescriptions (151 of 360) in 2024. A higher opioid share than 9 in 10 peers; the typical physician assistant clinician is at 1%.
351 generic and fewer than 11 brand-name prescriptions · $6,564 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.
