Drugs they prescribed that Part D paid
$13,481
Pharmacies billed $13,481 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 40% of their Part D prescriptions (132 of 330) in 2024. Above the middle of the specialty; the typical physician assistant clinician is at 1%. Long-acting opioids: 19% of their opioid prescriptions.
322 generic and fewer than 11 brand-name prescriptions · $13,481 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.
