Drugs they prescribed that Part D paid

$24,892

Pharmacies billed $24,892 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

Opioids were 3% of their Part D prescriptions (13 of 428) in 2024. At or below the middle of the specialty; the typical otolaryngology clinician is at 4%.

419 generic and fewer than 11 brand-name prescriptions · $24,892 in drug cost · 70 antibiotic prescriptions to 47 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.
