Overview
TRICARE billing is the claims-submission and revenue-cycle workflow for services provided to TRICARE beneficiaries — active-duty military and their dependents, military retirees, certain veterans, and eligible others. TRICARE is the Department of Defense healthcare program administered by the Defense Health Agency with regional contractors processing claims and managing networks. Current regional contractors are Humana Government Business (East Region) and TriWest Healthcare Alliance (West Region).
TRICARE has several plan variants. TRICARE Prime is the managed care option with enrolled beneficiaries and PCM (primary care manager) gatekeeping. TRICARE Select is the PPO-style option with broader choice and higher cost-sharing. TRICARE for Life (TFL) is the Medicare wraparound for retirees age 65+; Medicare is primary and TFL is secondary. TRICARE Reserve Select is for reservists. TRICARE Young Adult is for dependents 21–26. Each has its own cost-sharing, eligibility, and rules.
TRICARE claims submission uses standard 837 format with TRICARE-specific payer IDs. Network providers (in-network with TRICARE) follow the authorized rates schedule (CHAMPUS Maximum Allowable Charge, or CMAC — updated annually). Non-network authorized providers can bill but have higher cost-sharing to beneficiaries. Non-participating providers in most scenarios cannot balance-bill TRICARE beneficiaries beyond a limit; compliance with this is a common audit area.
Authorization and referral requirements vary by plan. TRICARE Prime generally requires PCM referral for specialist care; specialty services and behavioral health have specific authorization rules. TRICARE Select has fewer referral requirements but some services still need authorization. Hospital admissions have separate authorization requirements. Getting authorization wrong is a common denial cause; the regional contractors' provider portals list current authorization requirements per service.
Operationally, TRICARE billing complications include: DEERS-based eligibility (Defense Enrollment Eligibility Reporting System — the authoritative eligibility source for TRICARE), which periodically updates and can lag real eligibility changes; network status management across the two regional contractors; specific TRICARE-only services (military-related services, certain cosmetic rehabilitation); and claim-form variations for overseas care. The regional contractors' provider portals are the primary operational reference for TRICARE-specific rules.
TRICARE Billing is most operationally disruptive when a payer updates its published policy without a broad provider-facing announcement. The mitigation is pre-emptive monitoring of payer policy bulletins combined with a front-end flag that forces TRICARE Billing context into the intake workflow. Pairing TRICARE Billing review with medicare secondary payer and medicaid managed care in the same staleness report keeps the practice ahead of the per-payer churn cycle and compresses the feedback loop between a payer change and the corresponding claim-scrubber update.
From a contracting standpoint, TRICARE Billing is one of the payer attributes that should be renegotiated on every contract renewal, not left to default. Practices that ignore TRICARE Billing during negotiation leave money on the table via medicare secondary payer drift and medicaid managed care disputes that could have been prevented at the contract-language level. Reviewers maintain a change log against TRICARE Billing so the contracting team has evidence at hand during renewal discussions.

Worked example
A primary care practice sees a TRICARE Select beneficiary for an annual exam. The practice verifies DEERS eligibility, confirms in-network status with Humana Government (East Region), and submits the claim via 837 with the Humana TRICARE payer ID. Humana adjudicates at CMAC rates; member cost-sharing per TRICARE Select benefits; payment posts similar to any commercial claim.
Frequently asked questions — TRICARE Billing
Who is eligible for TRICARE?
Active-duty military and their dependents, military retirees and their dependents, members of the National Guard/Reserves in certain statuses, Medal of Honor recipients, eligible survivors, and certain others as defined by DoD. DEERS is the authoritative eligibility database.
What's the difference between TRICARE Prime and Select?
Prime is managed care with PCM (primary care manager) assignment, lower cost-sharing, and referral requirements. Select is PPO-style with broader network access, higher cost-sharing, and fewer referral requirements. Beneficiaries choose during enrollment.
How does TRICARE for Life work?
TFL is the Medicare wraparound for military retirees age 65+. Medicare is primary; TFL is secondary and typically covers Medicare coinsurance and deductibles. Claims are automatically crossed over from Medicare to TRICARE for most services, though providers should verify claim forwarding.
Can we balance-bill TRICARE beneficiaries?
Generally no beyond specific limits. Participating providers accept CMAC as payment in full. Non-participating authorized providers may have limited balance-billing in specific scenarios. Balance-billing rules are clarified in the TRICARE Operations Manual and the regional contractors' provider resources.
