Drugs they prescribed that Part D paid

$131,023

Pharmacies billed $131,023 in 2024.

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

Opioids were 1% of their Part D prescriptions (21 of 1,910) in 2024. Above the middle of the specialty; the typical neurology clinician is at 0%.

1,840 generic and fewer than 11 brand-name prescriptions · $131,023 in drug cost · 51 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.
