Drugs they prescribed that Part D paid

$4,127

Pharmacies billed $4,127 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 23) in 2024. Too few prescriptions to compare fairly with other clinicians.

20 generic and fewer than 11 brand-name prescriptions · $4,127 in drug cost · 19 antibiotic prescriptions to 14 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.
