Drugs they prescribed that Part D paid

$55,403

Pharmacies billed $55,403 in 2024.

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

Opioids were 36% of their Part D prescriptions (586 of 1,609) in 2024. Above the middle of the specialty; the typical physician assistant clinician is at 1%.

1,530 generic and 79 brand-name prescriptions · $55,403 in drug cost · 152 antibiotic prescriptions to 129 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.
