  • Only prescriptions filled by people with Medicare Part D drug coverage are counted. Private insurance, Medicaid and cash purchases are not.
  • CMS leaves out medications with fewer than 11 prescriptions and hides patient counts under 11.
  • Cost per fill is what the plan and the patient paid the pharmacy together, not what you pay at the counter.
  • Medication descriptions are summaries from CMS. They are not medical advice; ask a health care professional about any medication.
