Drugs they prescribed that Part D paid

$3,525

Pharmacies billed $3,525 in 2024.

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

Opioids were 16% of their Part D prescriptions (42 of 261) in 2024. Above the middle of the specialty; the typical physician assistant clinician is at 1%.

261 generic and 0 brand-name prescriptions · $3,525 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.
