Eligibility for military retirees
As a military retiree, you become eligible for TRICARE after completing the required years of service. Your eligibility may also extend to your spouse and certain dependent children. This eligibility allows you to enroll in various TRICARE health plans tailored to your retirement status, regardless of whether you are under or over the age of 65.
Programs included under TRICARE
TRICARE offers several programs for retirees:
- TRICARE Prime: Managed care similar to an HMO.
- TRICARE Select: Fee-for-service option with broader provider choice.
- TRICARE for Life: Designed to coordinate with Medicare (once eligible).
Each program has its own rules for enrollment, cost-sharing, and provider access.
How Does TRICARE Coordinate With FEHB?
Dual enrollment considerations
It is possible for federal retirees, especially those who transitioned from military to civilian federal service, to have access to both TRICARE and the Federal Employees Health Benefits (FEHB) Program. Dual enrollment gives you flexibility, but also requires thoughtful coordination to avoid unnecessary expenses or redundant coverage.
Claims and payment structure
When you have TRICARE and FEHB, one plan is typically designated as primary and the other as secondary. The primary plan pays first, while the secondary plan covers some or all of the remaining balance, depending on the coverage rules. Proper coordination can minimize out-of-pocket costs, but claim processes may be more complex and require you to file additional paperwork.
Coverage overlaps and gaps
Because TRICARE and FEHB offer similar health coverage, you may encounter overlaps in medical, pharmacy, and specialty care. However, there can also be gaps—certain services might be covered under one plan but not the other. Understanding what each program covers helps you ensure complete protection and avoid surprises.
What Happens When You Get Medicare?
Medicare eligibility for retirees
At age 65, or as you qualify by disability, you become eligible for Medicare. To keep TRICARE for Life, you must enroll in Medicare Part A and Part B. Medicare becomes your primary health coverage, with TRICARE for Life acting as secondary payer.
TRICARE and Medicare coordination
When you have both Medicare and TRICARE for Life, Medicare processes claims first. TRICARE for Life then covers most of the remaining costs, including copayments and deductibles for Medicare-approved services. It’s a seamless process for most providers who accept both plans, but you should always verify your provider accepts both Medicare and TRICARE.
FEHB and Medicare interaction
When you have all three—FEHB, TRICARE for Life, and Medicare—you have more coverage layers, but also a more complex claims process. Some retirees choose to suspend (not cancel) FEHB upon qualifying for Medicare and TRICARE for Life, retaining the option to reinstate FEHB later under special circumstances.
Pros of Coordinating TRICARE With Other Benefits
Enhanced coverage options
Having more than one health benefit program can broaden your coverage. Dual or triple coordination improves access to a wider network of providers, different forms of care, and greater protection against unexpected medical expenses.
Potential cost savings
When managed well, coordinating these programs can result in lower out-of-pocket expenses. Using one plan to offset the gaps in another can reduce your risk for large bills, especially during major health events or long-term treatments.
Provider flexibility
With multiple plans, you may enjoy expanded choices of doctors, hospitals, and specialists. This can be especially valuable if you live in different locations throughout the year or move after retirement.
What Are the Cons of Coordination?
Possible coverage complexity
It can be challenging to keep track of which plan pays for what and when you need to file claims yourself. Overlapping benefits and different rules about referrals, authorizations, or copayments might lead to confusion if you’re not proactive about managing your coverage.
Managing multiple benefit programs
Juggling TRICARE, FEHB, and Medicare means communicating with several agencies for enrollment, changes, or problem resolution. Keeping documentation organized and understanding the correct process for each situation is essential, but can feel overwhelming.
Annual enrollment decisions
Each year, you may need to review your coverage and decide if changes are needed. This review process can involve learning about premium adjustments, new benefits, and possible plan changes from FEHB carriers or government programs. Making the right choice requires staying informed and comparing your options regularly.
Is Keeping FEHB in Retirement Worth It?
FEHB as a secondary benefit
FEHB can serve as a valuable secondary safety net if you wish to broaden your coverage spectrum. It can fill in gaps or cover services not included under TRICARE or Medicare, such as certain international emergencies and benefits for family members not otherwise eligible for TRICARE.
When to suspend vs. cancel FEHB
Suspending your FEHB (instead of cancelling) when you enroll in Medicare and TRICARE for Life is an important distinction. Suspension means you keep the right to return to FEHB during a future open season or if your other coverage changes, while cancellation ends this benefit permanently. Suspension can give you flexibility without locking you into a single benefit program.
Factors impacting your decision
Deciding whether to keep, suspend, or drop FEHB depends on a variety of factors: your anticipated healthcare needs, risk tolerance, family situation, premium costs, and your age or stage of retirement. Taking the time to compare benefit summaries, out-of-pocket costs, and network needs will help guide your choice.
