Drugs they prescribed that Part D paid
$11,147
Pharmacies billed $11,147 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 25% of their Part D prescriptions (35 of 140) in 2024. Above the middle of the specialty; the typical physician assistant clinician is at 1%.
118 generic and 22 brand-name prescriptions · $11,147 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.
