Expanded 100-day medication supply benefit

In 2023, UnitedHealthcare Medicare Advantage members in all states except Alaska can receive 100-day supplies of medications for the same copay as 90-day supplies.¹

Recent studies show that 100-day medication supplies can help:

  • Drive greater medication adherence2
  • Save patients money — Same copay for a 100-day supply as a 90-day supply3
  • Improve access to medications with 24/7 access to a pharmacist,4 resulting in better patient experiences5
  • Maximize patients’ plan benefits
