Due to the TRICARE changes that went into effect Jan. 1, 2018, we currently are experiencing high call volumes. We offer many self-service tools on our website you can use to assist with your TRICARE transactions, as well as general information should you have questions about the recent changes to TRICARE. We appreciate your patience.
Your access to care is our priority. Please review the "Five Things to Know" for beneficiaries and providers.
The answers to your questions might be found on our website. We offer public and secure tools (log in required) to help you with your TRICARE transactions, including cost pages that explain the new copayment structure.
You can also use our Interactive Voice Response system for certain transactions, such as checking eligibility and making enrollment payments, rather than waiting on hold. Tip: If you have background noise when using the IVR, mute your phone and key in your responses.
