Drugs they prescribed that Part D paid
$21,217
Pharmacies billed $21,217 in 2024.

Opioids were 0% of their Part D prescriptions (0 of 26) in 2024. Too few prescriptions to compare fairly with other clinicians.
0 generic and 24 brand-name prescriptions · $21,217 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.
