Drugs they prescribed that Part D paid

$204,898

Pharmacies billed $204,898 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 1,095) in 2024. At or below the middle of the specialty; the typical physician assistant clinician is at 1%.

875 generic and 220 brand-name prescriptions · $204,898 in drug cost · 14 antibiotic prescriptions to 12 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.
