Drugs they prescribed that Part D paid

$19,676

Pharmacies billed $19,676 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 69) in 2024. At or below the middle of the specialty; the typical psychiatry clinician is at 0%.

47 generic and 22 brand-name prescriptions · $19,676 in drug cost.

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.
