Drugs they prescribed that Part D paid
$306
Pharmacies billed $306 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 54% of their Part D prescriptions (44 of 82) in 2024. A higher opioid share than 9 in 10 peers; the typical physician assistant clinician is at 1%.
82 generic and 0 brand-name prescriptions · $306 in drug cost · 12 antibiotic prescriptions.
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.
