Drugs they prescribed that Part D paid
$1,073
Pharmacies billed $1,073 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 11) in 2024. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.
$1,073 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.
