Drugs they prescribed that Part D paid

$511,865

Pharmacies billed $511,865 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 2,273) in 2024. At or below the middle of the specialty; the typical psychiatry & neurology clinician is at 0%.

2,164 generic and 109 brand-name prescriptions · $511,865 in drug cost · 126 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.
