Drugs they prescribed that Part D paid

$277,844

Pharmacies billed $277,844 in 2024.

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

Opioids were 16% of their Part D prescriptions (48 of 299) in 2024. Above the middle of the specialty; the typical physician assistant clinician is at 1%.

262 generic and 37 brand-name prescriptions · $277,844 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.
