Drugs they prescribed that Part D paid

$485

Pharmacies billed $485 in 2024.

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

Opioids were 30% of their Part D prescriptions (19 of 63) in 2024. A higher opioid share than 9 in 10 peers; the typical nurse practitioner clinician is at 0%.

63 generic and 0 brand-name prescriptions · $485 in drug cost · 28 antibiotic prescriptions to 24 people.

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.
