MedicareBlue Rx Standard Plan Formulary Changes for 2027

Nov. 11, 2026

Applies to Medicare Markets

The MedicareBlue℠ Rx (PDP) Standard Plan will transition to a different formulary in 2027. To support this transition, letters were mailed to affected members on Oct. 29, 2026, notifying them of formulary changes that may impact medications they have recently filled. The letter explains how the changes may affect their medications and outlines any actions they may need to take.

If members ask why they received this letter, you can explain that they received it because there will be changes to Medicare Part D prescription drug coverage effective Jan. 1, 2027. If they have additional questions, you can direct them to call Customer Service.
