Drugs they prescribed that Part D paid

$1,876,681

Pharmacies billed $1,876,681 in 2024.

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

Opioids were 5% of their Part D prescriptions (34 of 762) in 2024. Above the middle of the specialty; the typical nurse practitioner clinician is at 0%.

585 generic and fewer than 11 brand-name prescriptions · $1,876,681 in drug cost · 12 antibiotic prescriptions.

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.
