On March 16, 2012, TRICARE Management Activity selected UnitedHealthcare
Military & Veterans as the new TRICARE West Region contractor. TriWest
Healthcare Alliance protested the contract award but the protest was denied on
July 2, 2012.
As a result, UnitedHealthcare will provide health care under the new contract
beginning April 1, 2013.
Pharmacy, dental and TRICARE For Life contracts are not affected by the new West
TRICARE West Region
The West Region includes the states of Alaska, Arizona, California, Colorado,
Hawaii, Idaho, Iowa (except the Rock Island Arsenal area), Kansas, Minnesota,
Missouri (except the St. Louis area), Montana, Nebraska, Nevada, New Mexico,
North Dakota, Oregon, South Dakota, Texas (areas of Western Texas only), Utah,
Washington and Wyoming.
No Changes Until New Contract Begins
Meanwhile, nothing changes as TriWest continues to serve the 2.9 million
beneficiaries in the West Region until UnitedHealthcare begins healthcare
delivery. If you file your own claims, please continue to file them as you do
now for your care until April 1, 2013.
Your TRICARE benefits remain unchanged under the new contract. Please keep in
mind, however, that TRICARE benefits are always subject to change due to
Congressional legislation or adjustments in TRICARE policy.
Continuity of care remains a top TRICARE priority and the new contractor will
make every effort to conduct a smooth transition to new providers. However, some
TRICARE Prime and Prime Remote enrollees may have to change their primary care
manager when the new contract begins.
New claims filing and customer service addresses will be provided as the start
of health care delivery approaches.
