Drugs they prescribed that Part D paid

$277,152

Pharmacies billed $277,152 in 2024.

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

Opioids were 0% of their Part D prescriptions (0 of 865) in 2024. At or below the middle of the specialty; the typical psychiatry clinician is at 0%.

792 generic and 73 brand-name prescriptions · $277,152 in drug cost · 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.
