Drugs they prescribed that Part D paid

$64,435

Pharmacies billed $64,435 in 2024.

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

Opioids were 2% of their Part D prescriptions (12 of 786) in 2024. At or below the middle of the specialty; the typical family practice clinician is at 2%.

701 generic and fewer than 11 brand-name prescriptions · $64,435 in drug cost · 14 antibiotic prescriptions to 11 people · 11 antipsychotic prescriptions to people over 65.

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.
