Drugs they prescribed that Part D paid

$1,900

Pharmacies billed $1,900 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 99) in 2024. At or below the middle of the specialty; the typical otolaryngology clinician is at 4%.

97 generic and fewer than 11 brand-name prescriptions · $1,900 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.
