Drugs they prescribed that Part D paid
$4,410
Pharmacies billed $4,410 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 46% of their Part D prescriptions (92 of 200) in 2024. Above the middle of the specialty; the typical orthopedic surgery clinician is at 31%.
197 generic and fewer than 11 brand-name prescriptions · $4,410 in drug cost · 43 antibiotic prescriptions to 18 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.
