Drugs they prescribed that Part D paid
$430
Pharmacies billed $430 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 45) in 2024. Too few prescriptions to compare fairly with other clinicians.
43 generic and fewer than 11 brand-name prescriptions · $430 in drug cost · 34 antibiotic prescriptions to 22 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.
