Drugs they prescribed that Part D paid
$76,705
Pharmacies billed $76,705 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 971) in 2024. At or below the middle of the specialty; the typical psychiatry clinician is at 0%.
940 generic and 31 brand-name prescriptions · $76,705 in drug cost · 145 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.
