Drugs they prescribed that Part D paid

$46,318

Pharmacies billed $46,318 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 1,014) in 2024. At or below the middle of the specialty; the typical nurse practitioner clinician is at 0%.

990 generic and 24 brand-name prescriptions · $46,318 in drug cost · 51 antipsychotic prescriptions to people over 65.

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.
