Drugs they prescribed that Part D paid
$1,757
Pharmacies billed $1,757 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 0% of their Part D prescriptions (0 of 72) in 2024. At or below the middle of the specialty; the typical dermatology clinician is at 0%.
71 generic and fewer than 11 brand-name prescriptions · $1,757 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.
