Drugs they prescribed that Part D paid

$50,900

Pharmacies billed $50,900 in 2024.

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

Opioids were 1% of their Part D prescriptions (14 of 1,013) in 2024. At or below the middle of the specialty; the typical family practice clinician is at 2%.

949 generic and fewer than 11 brand-name prescriptions · $50,900 in drug cost · 22 antibiotic prescriptions to 13 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.
