TRICARE For Life Claim Denied: How to Appeal

TRICARE For Life (TFL) is a valuable benefit for military retirees and their dependents who are entitled to Medicare. TFL acts as a secondary payer to Medicare, covering most of what Medicare does not — effectively eliminating most out-of-pocket costs for eligible beneficiaries. When a TFL claim is denied, it is often due to a Medicare primary claim issue, a billing error, or a misunderstanding of how the two programs interact. Here is how to understand your benefits and appeal a denial.

What Is TRICARE For Life?

TRICARE For Life is automatic coverage available to military retirees (and eligible dependents) who are:

• Entitled to Medicare Part A (generally based on age 65, or disability)
• Enrolled in Medicare Part B
• Registered in the Defense Enrollment Eligibility Reporting System (DEERS)

There is no additional premium for TFL beyond the Medicare Part B premium. TFL works automatically — you do not need to file separate claims in most cases. When you receive care from a Medicare-participating provider, Medicare processes the claim first, then automatically transmits it to TRICARE for secondary payment.

How TFL Coordinates with Medicare

Standard coordination:

1. Medicare pays its share (typically 80% of the approved amount after the deductible)
2. Medicare transmits the claim to TRICARE automatically
3. TFL pays most or all of the remaining Medicare cost-sharing (the 20% coinsurance and often the deductible)

For most Medicare-covered services from Medicare-participating providers, beneficiaries end up paying very little or nothing out-of-pocket.

TFL is not available for services Medicare doesn't cover: If Medicare denies a claim, TFL generally will not pay either. The exception is services that TFL covers independently of Medicare (see below).

Prior Authorization Denied: How to Appeal" class="auto-link">Prior Authorization: Mostly Not Required for TFL

Unlike many insurance plans, TRICARE For Life generally does not require prior authorization for most services covered under the Medicare benefit. This is one of TFL's significant advantages over Medicare Advantage plans.

However, prior authorization is required for certain TFL-exclusive benefits (services TFL covers that Medicare does not). These may include:

• Certain skilled nursing facility care beyond what Medicare covers
• Home health services beyond Medicare's coverage
• Some overseas coverage situations

Check your TRICARE For Life handbook or contact your TRICARE regional contractor for the current prior authorization requirements.

What TFL Covers That Medicare Does Not

TFL provides some benefits that Medicare does not cover or covers only partially:

• Overseas coverage: TFL covers care received overseas (Medicare generally does not cover overseas care). This is a significant benefit for retirees who live or travel abroad
• Additional pharmacy benefits: Through the TRICARE Pharmacy program, TFL beneficiaries can access prescriptions through military pharmacies, the TRICARE Mail Order Pharmacy (Express Scripts), and retail network pharmacies, often at lower costs than Medicare Part D
• Some extended skilled nursing care: TFL may cover SNF days that Medicare's 150-day benefit does not cover in certain circumstances
• Certain services in MTFs: Care at Military Treatment Facilities (MTFs) for space-available TFL beneficiaries

Common Reasons TFL Claims Are Denied

1. Medicare Denied the Primary Claim TFL cannot pay as secondary if Medicare did not pay as primary. If Medicare denied the underlying claim, TFL will follow. Address the Medicare denial first.

2. Provider Not Medicare-Participating If your provider does not accept Medicare assignment, the claim may not flow through the standard crossover process correctly. Using Medicare-participating providers ensures smooth TFL processing.

3. DEERS Enrollment Issue TFL requires active DEERS enrollment. If your DEERS information is outdated or incorrect — wrong Medicare number, expired enrollment data — claims may be denied. Update your DEERS information at a military ID card office or online through milConnect.

4. Part B Not Enrolled TFL requires Medicare Part B enrollment. If you are not enrolled in Part B, you are not eligible for TFL. Ensure your Part B enrollment is active.

5. Claims Not Crossing Over If the automatic Medicare-to-TRICARE crossover fails, you can file TFL claims manually. Submit an EOB)" class="auto-link">explanation of benefits from Medicare to your TRICARE regional contractor.

The TRICARE For Life Appeal Process

Step 1 — Address the Medicare Denial First If Medicare denied the claim, appeal the Medicare denial (using the Medicare 5-level appeal process). Once Medicare pays, TFL should follow automatically.

Step 2 — Contact Your TRICARE Regional Contractor For TFL-specific denials, contact your TRICARE regional contractor (Humana Military for most regions, HealthNet Federal Services for others). Contact information is on your Explanation of Benefits.

Step 3 — File a TRICARE Formal Complaint or Claim Dispute Submit a written dispute to your TRICARE contractor. Include your Medicare EOB, the TRICARE denial notice, and an explanation of why the claim should be paid.

Step 4 — TRICARE Appeal to Defense Health Agency (DHA) If your contractor dispute is unsuccessful, file an appeal with the Defense Health Agency (DHA), which oversees TRICARE. DHA review is the final administrative level for TRICARE disputes.

Step 5 — Congressional Inquiry For significant unresolved issues, contacting your U.S. Congressional representative's office can be effective. Congressional casework offices routinely assist military families with TRICARE disputes.
