Drugs they prescribed that Part D paid
$7,321
Pharmacies billed $7,321 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 32% of their Part D prescriptions (202 of 630) in 2024. Above the middle of the specialty; the typical physician assistant clinician is at 1%.
626 generic and fewer than 11 brand-name prescriptions · $7,321 in drug cost · 174 antibiotic prescriptions to 149 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.
