TRICARE Contractor Apologizes for OHI Errors Affecting 4 Million Beneficiaries

TriWest Healthcare Alliance apologized to more than 4 million TRICARE beneficiaries for errors in its patient portals that incorrectly showed they had Other Health Insurance, causing claim denials and delays amid the 2025 transition of TRICARE administration to TriWest. The move follows NBC News reporting of ongoing coverage problems and includes a case where a veteran’s cancer treatment was disrupted by denied claims. TriWest says OHI-related denials dropped from 2.3% to 1.3% and pledges further fixes, noting that testing before go-live faced unforeseen challenges acknowledged by the Defense Health Agency.
