Drugs they prescribed that Part D paid

$737,289

Pharmacies billed $737,289 in 2024.

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

Opioids were 2% of their Part D prescriptions (16 of 833) in 2024. Above the middle of the specialty; the typical neurology clinician is at 0%. Long-acting opioids: 75% of their opioid prescriptions.

735 generic and fewer than 11 brand-name prescriptions · $737,289 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.
