TRICARE Changes Expected in 2024 > TRICARE Newsroom > Articles

A new TRICARE contract that facilitates health care for civilian beneficiaries, known as T-5, is expected to begin in 2024. The changes will improve the delivery, quality and cost of health care services for service members, retirees, and their families.

There will continue to be two regional performers. On December 22, 2022, the Defense Healthcare Agency (DHA) announced that Humana Government Business and TriWest Healthcare Alliance Corporation will be the regional contractors, also known as managed care maintenance contractors. If you live in the TRICARE East region, Humana Government Business (Humana Military) will administer your health plan and provide TRICARE coverage. If you live in the TRICARE West region, TriWest Healthcare Alliance Corporation will administer your health plan and provide TRICARE coverage.

“I am pleased that our new T-5 TRICARE contracts will continue to focus on improving the care experience and great health care outcomes for our service members, retirees and their families,” said Lt. Gen. Ronald Place, the agency’s director of Defense Health.

Six states move to the West Region

The biggest change is the move of six states from the East Region to the West Region. This will affect approximately 1.5 million beneficiaries. The states moving from the East to the West region are:

  • Arkansas
  • Illinois
  • Louisiana
  • Oklahoma
  • Texas
  • Wisconsin

Moving these six states to the Western Region will create a more even balance of the TRICARE population managed by each regional contractor. The move will also streamline processes and standards for both regions.

What does this mean for you? DHA has scheduled the changes to take place in January 2024. In 2023, the same regional contractor will continue to manage your TRICARE health plan:

You do not need to take any action at this time. The way you get your health care will not change during the transition period until 2023. If you live in one of the states that is transitioning from the East to the West region, DHA and TRICARE regional contractors have different communications planned throughout the year . You’ll learn how the transition will happen – and all the steps you need to take – so your TRICARE benefits can continue smoothly.

Be sure to check the Defense Enrollment Eligibility Reporting System (DEERS) to confirm that all of your information is current. This will help make sure you don’t miss important communications about your TRICARE benefit.

The new contract focuses on care

The new contract includes a permanent commitment to improve access and quality of health services. Regional contractors will do this in a variety of ways, including:

  • Fostering innovation and best practice in the healthcare sector
  • Creating effective ways to reduce health care costs
  • Providing a basis for future health demonstrations and pilot projects
  • Improving how military hospitals and clinics and civilian care can work together to improve the patient healthcare experience

Some of the TRICARE health plan changes will happen behind the scenes, but each change will help support you by providing:

  • More efficient referral transfers between the two regions
  • Greater provider network flexibility
  • Improved beneficiary selection
  • Improved telehealth appointments

“DHA wants to improve your healthcare experience and ensure a smooth and timely transition for you and your family,” Place added.

Stay tuned

The transition planning time is planned for one full year. This is to ensure that healthcare delivery is ready for all 9.6 million beneficiaries on day one of the new contract. Expect valuable information about upcoming changes. Sign up for email notifications from TRICARE.
