Drugs they prescribed that Part D paid
$19,884
Pharmacies billed $19,884 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 7% of their Part D prescriptions (16 of 222) in 2024. Above the middle of the specialty; the typical physician assistant clinician is at 1%.
178 generic and 44 brand-name prescriptions · $19,884 in drug cost · 23 antibiotic prescriptions to 20 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.
