VA healthcare benefits and Tricare in conjunction

Yes, as a 100% disabled veteran married to an active-duty service member, you are eligible for and can use both VA healthcare and TRICARE Select concurrently; this is considered "dual eligibility," not prohibited "double coverage." Your VA care is primary for your service-connected conditions, while TRICARE can serve as a crucial secondary payer for non-service-connected care, VA copays, or when seeking care outside the VA network, governed by coordination of benefits rules under 38 CFR 17.1005 and the TRICARE policy manual. Your spouse must enroll you in DEERS as a family member, after which you can enroll in TRICARE Select (or Prime) through the Defense Health Agency—your VA disability compensation does not affect this eligibility. For actionable next steps, first ensure your DEERS enrollment is complete with your marriage certificate and ID; if the base office is unhelpful, escalate to the DEERS Support Office (1-800-538-9552). Simultaneously, maintain your VA enrollment (as your 100% rating guarantees Priority Group 1) and present your VA Health Identification Card (VHIC) at VA facilities and your TRICARE ID when using civilian providers. Proactively provide both insurance details to any non-VA providers to ensure proper billing coordination and avoid out-of-pocket costs. **Disclaimer: This is educational information for claims assistance and should not be construed as legal, medical, or official benefits advice; for definitive guidance, consult the VA Health Benefits Advisor and TRICARE contractor.**
