Drugs they prescribed that Part D paid
$6,706
Pharmacies billed $6,706 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 19% of their Part D prescriptions (20 of 107) in 2024. Above the middle of the specialty; the typical physician assistant clinician is at 1%.
89 generic and 18 brand-name prescriptions · $6,706 in drug cost · 48 antibiotic prescriptions to 28 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.
