Drugs they prescribed that Part D paid
$7,010
Pharmacies billed $7,010 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 234) in 2024. At or below the middle of the specialty; the typical psychiatry clinician is at 0%.
230 generic and fewer than 11 brand-name prescriptions · $7,010 in drug cost · 14 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.
