Tricare for Life is a healthcare program designed for eligible military retirees and their families, but it's often misunderstood as a Medicare supplement. In reality, it's a separate program that works in conjunction with Medicare, but with some key differences.
Tricare for Life is not a Medicare supplement, but rather a Medicare wraparound program. This means that it's designed to fill in the gaps in Medicare coverage, rather than duplicating it.
Eligible military retirees and their families can enroll in Tricare for Life, which is a voluntary program. To qualify, you must be 65 or older and have both Medicare Part A and Medicare Part B.
Suggestion: Fehb and Medicare Part D
Eligibility and Enrollment
To be eligible for TRICARE for Life, you must have Medicare Part A and Medicare Part B, also known as Original Medicare. You'll also need to have your information up to date with DEERS to automatically enroll in TRICARE for Life without an enrollment fee.

You can remain eligible for TRICARE without enrolling in Medicare Part B only if you're an active duty service member, an active duty family member, or enrolled in certain TRICARE plans such as TRICARE Reserve Select or TRICARE Young Adult.
Most people with TRICARE who become Medicare eligible must also have Medicare Part B to remain eligible, but you can enroll in Part D at any time if you choose to, and the TRICARE drug benefit is considered creditable coverage.
Eligibility Requirements
To be eligible for TRICARE for Life, you must be enrolled in Medicare Part A and Medicare Part B, also known as Original Medicare. These parts are required for automatic enrollment in TRICARE for Life, as long as your information is up to date with DEERS.
You must also be enrolled in Medicare Part B to remain eligible for TRICARE, unless you meet certain exceptions. These exceptions include being an active duty service member, an active duty family member, or enrolled in TRICARE Reserve Select, TRICARE Retired Reserve, TRICARE Young Adult, or the US Family Health Plan.
TRICARE for Life is a wraparound coverage for TRICARE-eligible beneficiaries who have Medicare Part A and Part B. This means that Medicare and TRICARE for Life coverage work together to help pay medical bills for retired and active-duty military personnel and families.
If you have beneficiaries who are younger than age 65 years and don’t yet qualify for Medicare, they aren’t personally eligible for TRICARE for Life yet. Other TRICARE policies are available for people under age 65 years who don’t qualify for Medicare.
Here's a summary of the eligibility requirements for TRICARE for Life:
- Enrolled in Medicare Part A and Medicare Part B
- Exceptions include being an active duty service member, an active duty family member, or enrolled in TRICARE Reserve Select, TRICARE Retired Reserve, TRICARE Young Adult, or the US Family Health Plan
- Beneficiaries under age 65 years are not eligible for TRICARE for Life
On Active Duty
If you're on active duty, TRICARE will pay first for Medicare-covered services. This means you'll get the most out of your healthcare benefits.
TRICARE will pay the Medicare deductible and coinsurance for covered services. It's like having extra protection for your medical expenses.
TRICARE will also cover any services it covers, but Medicare doesn't. This can be a big relief if you need specialized care.
How It Works
TRICARE for Life is a secondary health care plan that supplements Medicare for those who are both TRICARE-eligible and have enrolled in Medicare Part A and B.
It's designed to help reduce your out-of-pocket costs when you're eligible for Medicare, and it provides overseas benefits, which can be helpful if you frequently travel out of the country.
TRICARE for Life will play a secondary role to Medicare, and healthcare providers will first file claims with Medicare and then send claims to TRICARE for additional processing.
This means that TRICARE will pay the provider directly for any services that were not covered by Medicare and are TRICARE-covered services.
Here's a breakdown of how TRICARE for Life works with Medicare plans:
You only need your Medicare plan card and military ID as proof of coverage, and you won't receive a TRICARE wallet card.
TRICARE for Life includes a prescription drug benefit, so you may not need Medicare Part D coverage.

Coverage and Costs
Choosing the right coverage can be a bit confusing, but it's mainly about deciding what services you want or need. TRICARE for Life can significantly reduce out-of-pocket costs, but it might not cover everything Medicare Advantage does.
You can also purchase additional policies like Medicare supplement insurance (Medigap) or Medicare Part D plans through private insurance companies. These can help reduce overall healthcare costs.
Here's a simplified breakdown of how Medicare and TRICARE For Life pay healthcare costs:
- Providers file claims with Medicare.
- Medicare pays its portion and sends the claim to the TRICARE For Life claims processor.
TRICARE For Life pays its portion directly to the provider for covered services.

Health Care Costs
Health care costs can be a significant concern, especially when navigating multiple insurance plans. TRICARE for Life can significantly reduce your out-of-pocket costs, but it may not cover all services that Medicare Advantage does.
You can also purchase additional policies, such as Medicare supplement insurance (Medigap) or Medicare Part D plans through private insurance companies, to help reduce overall healthcare costs.
To understand how Medicare and TRICARE For Life pay health care costs, it's essential to know that Medicare will be the primary payer in the U.S. and U.S. Territories. Here's how it works:
1. The provider will file the claim(s) with Medicare.
2. Medicare will then pay the portion it’s responsible for and then send the claim to the TRICARE For Life claims processor.
3. TRICARE For Life will pay its portion directly to the provider for the services TRICARE covers.
If you receive TRICARE-eligible services overseas, Medicare won’t contribute anything towards paying your claims. You’ll be responsible for paying TFL’s deductible and cost-shares along with the balance of any bills from providers.
TRICARE pays after Medicare in the United States and in U.S. territories, but Medicare generally doesn’t offer coverage outside the U.S. and U.S. territories. There are three rare exceptions to foreign coverage:
- You live within the United States, but the closest hospital that can handle your medical emergency lies outside the United States.
- You live within the United States, but the closest hospital that can treat your health condition lies outside the United States.
- You’re traveling through Canada to move between Alaska and another U.S. state, and you need to stop at a Canadian hospital to treat an illness or injury without an unreasonable delay.
How to Choose the Right Coverage
Choosing the right coverage can be a complex task, especially when you have multiple options to consider. TRICARE for Life can significantly reduce your out-of-pocket costs, but it may not cover some services that Medicare Advantage does.
You can purchase additional policies, such as Medicare supplement insurance (Medigap) or Medicare Part D plans through private insurance companies. These may help reduce your overall healthcare costs.
If you're considering TRICARE for Life and Medicare Advantage, it's essential to understand how having both policies may affect you. You'll need to consider factors like prescription drug coverage, healthcare networks, and costs.
Here are some key considerations to keep in mind:
- Prescription drug coverage: TRICARE for Life offers prescription drug coverage, so do many Medicare Advantage plans. If you don't want dual coverage, you can choose a Medicare Advantage plan that doesn't offer prescription drug benefits.
- Healthcare networks: You'll usually experience the greatest cost savings in Medicare Advantage if you use in-network doctors and facilities. This is usually a smaller network than you would have with Original Medicare or TRICARE for Life.
- Costs: Some Medicare Advantage plans are premium-free, but others are not. Most plans will require you to pay a copayment when you see in-network doctors. Often, TRICARE for Life will pay the costs of these copayments.
By understanding these factors, you can make an informed decision about the right coverage for your needs.
