-
Navigating Medicare alongside TRICARE for Life can be complex, but knowing how enrollment, coverage, and cost-sharing work will help you make informed decisions.
Understanding How TRICARE for Life Works with Medicare
As a military retiree, you’ve earned access to TRICARE for Life (TFL), which acts as wraparound coverage to Medicare. But figuring out how these two programs interact can be confusing. Medicare becomes your primary insurance, while TFL serves as secondary coverage, helping to cover the costs that Medicare doesn’t fully pay.

Enrollment Requirements: What You Need to Do
If you’re approaching your 65th birthday, you must enroll in Medicare Part A and Part B to maintain your TFL coverage. Here’s what you need to know:
-
When to Enroll: Your Initial Enrollment Period (IEP) starts three months before your 65th birthday and lasts for seven months. You must enroll during this period to avoid coverage gaps or late penalties.
-
What Happens if You Delay? If you don’t enroll in Part B on time, you may lose your TFL benefits until you sign up for Medicare. Plus, you’ll face a late enrollment penalty that increases your premium for life.
-
Special Enrollment Period (SEP): If you are still working and covered under a credible employer health plan, you can delay Part B enrollment until you retire without facing penalties. However, once you retire, you must enroll in Part B within eight months to avoid gaps in coverage.
1. How Your Coverage Works in Different Scenarios
TFL and Medicare work together, but how they cover you depends on where you receive care and whether Medicare covers the service.
Medicare-Covered Services
If a service is covered by Medicare, it pays first, and TFL covers the remaining costs. This includes:
-
Doctor visits, outpatient care, and lab tests
-
Hospital stays and skilled nursing facility care
-
Medical equipment and preventive care
With this combination, you rarely pay out-of-pocket expenses except for services not covered by either program.
Services Not Covered by Medicare
TFL may still cover some services that Medicare does not, such as certain prescription drugs or overseas care. However, TFL does not cover routine dental, vision, or hearing services, so you may need a separate plan for those.
Overseas Care Considerations
One major benefit of TFL is overseas coverage. Unlike Medicare, which generally does not cover care outside the U.S., TFL provides reimbursement for certain medical services abroad. If you live or travel internationally, TFL can help you access care when needed.
2. Costs and How to Minimize Expenses
Even with Medicare and TFL, it’s important to understand your financial responsibilities.
Medicare Part B Premiums
Since Medicare is your primary insurance, you must pay the Part B premium, which is $185 per month in 2025. This cost is unavoidable, as failing to pay it could result in losing your TFL coverage.
Prescription Drug Costs
TRICARE for Life includes TRICARE Pharmacy Benefits, which cover many prescription drugs. If you have Medicare Part D, TFL may help pay for medications that Medicare does not fully cover. However, since TFL already has strong pharmacy coverage, many beneficiaries don’t need a Part D plan.
Managing Out-of-Pocket Costs
To reduce your healthcare expenses:
-
Use TRICARE-authorized providers who accept Medicare.
-
Stay within Medicare’s network to ensure your claims are processed correctly.
-
Review annual changes to your Medicare and TFL benefits to stay informed about any cost updates.
3. Common Misconceptions About TRICARE for Life and Medicare
“I Don’t Need Medicare Since I Have TRICARE for Life”
False. Medicare is your primary coverage at 65 and beyond. Without Medicare, you cannot keep TFL.
“I Need to Enroll in Medicare Advantage for Extra Coverage”
Not necessarily. Medicare Advantage plans don’t work well with TFL. TFL already covers what Medicare doesn’t, so an Advantage plan could lead to unnecessary costs.
“TRICARE for Life Covers Everything”
While TFL is robust, it does not cover dental, vision, or long-term care. You may need additional plans for these services.
4. Planning for the Future: What You Need to Know Beyond Age 65
As you continue using Medicare and TFL, it’s crucial to reassess your healthcare needs periodically.
Annual Medicare Changes
Each year, Medicare updates its costs, coverage rules, and provider networks. Stay informed about changes to premiums, deductibles, and covered services so you can adjust your healthcare strategy as needed.
Long-Term Care Planning
Medicare and TFL do not cover long-term custodial care (like nursing homes or assisted living). If you anticipate needing long-term care, you may want to explore additional coverage options such as long-term care insurance or VA benefits.
Reviewing Your Benefits Annually
Make sure to review your TFL and Medicare benefits at least once a year to:
-
Ensure you are using the best available providers.
-
Adjust to any new cost-sharing requirements.
-
Confirm that your pharmacy coverage meets your medication needs.
