Drugs they prescribed that Part D paid

$4,912

Pharmacies billed $4,912 in 2024.

Opioids were 59% of their Part D prescriptions (285 of 480) in 2024. A higher opioid share than 9 in 10 peers; the typical physician assistant clinician is at 1%.

478 generic and fewer than 11 brand-name prescriptions · $4,912 in drug cost · 57 antibiotic prescriptions to 45 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.
