I’m a retired Illinois state employee. How does my state retiree Medicare Advantage coverage work?
Answered by 5 licensed agents
TRAIL is a state-sponsored Medicare Advantage Prescription Drug PPO plan. To participate, you must be enrolled in Medicare Parts A and B, and you continue paying your Medicare Part B premium.
Once TRAIL begins, the plan handles your hospital, doctor and prescription claims instead of Original Medicare. It combines your Part A, Part B and Part D prescription coverage into one retiree plan. Vision coverage is also included, with dental available separately.
The PPO is somewhat different from many traditional Medicare Advantage networks. You may generally see any provider who participates in Medicare and accepts the TRAIL plan, and the 2026 plan uses the same member cost-sharing whether that provider is in or out of the plan’s network.
Your share of the retiree premium depends in part on your years of state service. For 2026, retirees with 20 or more years of qualifying service receive the medical, prescription and vision portion without a retiree premium, while retirees with fewer years contribute toward the cost.
The simplest way to think about it is: you keep Medicare Parts A and B, but TRAIL becomes the plan you use for your medical and prescription coverage.

For 2026, Medicare-eligible State Employees’ Group Insurance Program retirees who elect TRAIL are covered through an Aetna Medicare Advantage Prescription Drug PPO, or MAPD plan.
You must remain enrolled in Medicare Parts A and B and continue paying your Medicare Part B premium. Once your TRAIL coverage begins, Aetna processes your medical and prescription drug claims rather than Original Medicare.
One important feature is that this is a PPO designed for State of Illinois retirees. The plan is available nationwide, and members may see providers who participate in Medicare and accept the plan. That can be especially important for retirees who travel or spend part of the year outside Illinois.
TRAIL also combines hospital, medical, and Part D prescription drug coverage into one plan, along with additional benefits provided through the State program.
Here is the part I would not overlook:
Your TRAIL coverage is an employer-sponsored retiree benefit. I would not compare it to an individual Medicare Advantage plan based only on premiums, copays, or extra benefits.
Before leaving or changing State retiree coverage, understand how that decision affects your TRAIL eligibility, prescription coverage, dependents, and your ability to return to the program.
For an Illinois state retiree, the question is not simply, “Can I find another Medicare plan?”
The better question is, “What am I receiving through my State retiree benefits, and what would I be giving up if I changed it?”

Thank you for your inquiry. Greatly appreciated. While I'm licensed in PA only, Medicare Advantage (MA) plans are very much thr same. They are not state run. They are set by the insurance carrier, such as Cigna, Aetna, etc. Depending on the MA plan you would have, you could have an MA with prescription drug coverage. That type of plan is known as an MAPD plan. An MA plan can also have Dental, Hearing, and Vision coverage. With an MA plan, even though you would be on Medicare, the MA plan takes precedent over Medicare. In other words, Medicare doesn't come into play when you have a doctor's appointment, which is taken care by your MA plan. Thanks again for your question.
