Drugs they prescribed that Part D paid

$490

Pharmacies billed $490 in 2024.

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

Opioids were 33% of their Part D prescriptions (27 of 83) in 2024. At or below the middle of the specialty; the typical hand surgery clinician is at 47%.

83 generic and 0 brand-name prescriptions · $490 in drug cost · 40 antibiotic prescriptions to 35 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.
