The State of Illinois offers retirees, annuitants, and survivors (of the State Employees Group Insurance Program (SEGIP), The Teachers' Retirement Insurance Program (TRIP), and the College Insurance Program (CIP)) a healthcare program entitled Total Retiree Advantage Illinois (TRAIL). This program provides Medicare-eligible members and their covered dependents comprehensive medical and prescription drug coverage through TRAIL Medicare Advantage Prescription Drug (commonly referred to as "MAPD") plans.

For members who are newly eligible for Medicare, you will have two opportunities for enrollment:

Initial Enrollment (IE): this is offered to all Medicare-eligible retirees and their Medicare-eligible dependents within 60-days of the 65th birthday (of the youngest enrollee). Initial enrollment is a one-time offering.

Open Enrollment (OE): an annual enrollment period held in the fall of each year. This enrollment period is open for Medicare-eligible retirees, survivors, and their dependents to change their elections, or for anyone who previously waived or canceled coverage to re-enroll.


To be eligible for coverage under a Total Retiree Advantage Illinois Medicare Advantage

Prescription Drug (MAPD) plan, you and your eligible dependents must:

• Live in the United States or the U.S. Territories, AND

• Be retired and enrolled in Medicare Parts A and B, due to age or disability.

Review the eligibility criteria and an explanation of the benefits provided through the Program.

During both opportunities for enrollment (IE & OE), retirees and survivors eligible for the TRAIL MAPD Program will receive a Decision Guide in the mail, notifying them of their eligibility and the requirement to enroll or waive coverage, during the TRAIL MAPD Open Enrollment Period. 

Note: Members who are currently enrolled in TRAIL MAPD, you do not need to do anything during the Open Enrollment Period.
