Drugs they prescribed that Part D paid
$706
Pharmacies billed $706 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 20% of their Part D prescriptions (11 of 56) in 2024. At or below the middle of the specialty; the typical orthopedic surgery clinician is at 31%. Surgeons prescribe little besides pain medicine after an operation, so their opioid share runs high.
56 generic and 0 brand-name prescriptions · $706 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.
