Drugs they prescribed that Part D paid
$3,021
Pharmacies billed $3,021 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 0% of their Part D prescriptions (0 of 306) in 2024. At or below the middle of the specialty; the typical nurse practitioner clinician is at 0%.
287 generic and 19 brand-name prescriptions · $3,021 in drug cost · 158 antibiotic prescriptions to 140 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.
