Drugs they prescribed that Part D paid

$1,936

Pharmacies billed $1,936 in 2024.

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

Opioids were 10% of their Part D prescriptions (34 of 328) in 2024. At or below the middle of the specialty; the typical oral surgery (dentist only) clinician is at 22%.

326 generic and fewer than 11 brand-name prescriptions · $1,936 in drug cost · 156 antibiotic prescriptions to 124 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.
