This is pharmacy cost, not the office bill, and not what patients paid.

Opioids were 0% of their 18 Part D prescriptions in 2023. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.

Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.
