Drugs they prescribed that Part D paid

$7,065,874

Pharmacies billed $7,065,874 in 2024.

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

Opioids were 4% of their Part D prescriptions (45 of 1,215) in 2024. Above the middle of the specialty; the typical nurse practitioner clinician is at 0%. Long-acting opioids: 40% of their opioid prescriptions.

626 generic and fewer than 11 brand-name prescriptions · $7,065,874 in drug cost · 44 antibiotic prescriptions to 25 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.
