Drugs they prescribed that Part D paid

$5,381

Pharmacies billed $5,381 in 2024.

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

Opioids were 42% of their Part D prescriptions (118 of 284) in 2024. A higher opioid share than 9 in 10 peers; the typical physician assistant clinician is at 1%.

277 generic and fewer than 11 brand-name prescriptions · $5,381 in drug cost · 41 antibiotic prescriptions to 34 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.
