Drugs they prescribed that Part D paid

$739

Pharmacies billed $739 in 2024.

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

Opioids were 32% of their Part D prescriptions (21 of 65) in 2024. A higher opioid share than 9 in 10 peers; the typical neurology clinician is at 0%.

65 generic and 0 brand-name prescriptions · $739 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.
