Drugs they prescribed that Part D paid
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 71% of their 98 Part D prescriptions in 2016. Surgeons prescribe little besides pain medicine after an operation, so their opioid share runs high.
Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.
