Upcoming Changes Total Retiree Advantage Illinois (TRAIL) Medicare Advantage Prescription Drug (MAPD) enrollment

Retired members and dependents who are eligible to enroll in Medicare Parts A and B are also required to enroll in a TRAIL Medicare Advantage Prescription Drug (MAPD) Program.  Effective July 1, 2025, you or your dependent will be required to enroll in the TRAIL MAPD plan when you are first eligible for Medicare, either by age or disability. 

If you are a State Retiree and you currently cover 2 or more dependents, you nor your Medicare eligible dependent(s) will be required to enroll in the TRAIL MAPD plan until there is only one covered dependent remaining or all covered dependents are Medicare eligible.

What do I need to do?

• Contact Social Security and enroll in Medicare Part A and B three months prior to your 65th birth month. If you are Medicare eligible, failure to enroll in Part A and Part B will result in a reduction of eligible claim benefits.
• During the Benefit Choice Open Enrollment period in May or when enrollment notice is received, the Medicare eligible member or dependent will be required to enroll in the TRAIL MAPD plan. Failure to enroll will result in the termination of coverage for the member and any covered dependents. If the dependent is eligible, failure to enroll will result in the termination of the dependent’s coverage.
