Drugs they prescribed that Part D paid
$27,906
Pharmacies billed $27,906 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 12% of their Part D prescriptions (11 of 96) in 2024. Above the middle of the specialty; the typical physician assistant clinician is at 1%.
71 generic and 25 brand-name prescriptions · $27,906 in drug cost · 22 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.
