Drugs they prescribed that Part D paid

$103,714

Pharmacies billed $103,714 in 2024.

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

Opioids were 0% of their Part D prescriptions (0 of 1,073) in 2024. At or below the middle of the specialty; the typical physician assistant clinician is at 1%.

912 generic and 148 brand-name prescriptions · $103,714 in drug cost · 39 antibiotic prescriptions to 29 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.
