Drugs they prescribed that Part D paid
$881,599
Pharmacies billed $881,599 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 7% of their Part D prescriptions (20 of 280) in 2024. Above the middle of the specialty; the typical student in an organized health care education/training program clinician is at 0%.
184 generic and fewer than 11 brand-name prescriptions · $881,599 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.
