Drugs they prescribed that Part D paid

$221

Pharmacies billed $221 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 18) in 2024. Too few prescriptions to compare fairly with other clinicians.

18 generic and 0 brand-name prescriptions · $221 in drug cost.

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.
