Change Healthcare (CHC), owned by United Healthcare and Optum, discovered its systems were under cyberattack
On February 21, 2024, Change Healthcare (CHC), owned by United Healthcare and Optum, discovered its systems were under cyberattack, resulting in disruption in service to its health plan and medical provider clients.
Alliant Health Plans (Alliant) uses Change Healthcare for its clearinghouse and electronic eligibility verification (270/271 feeds). The following functions managed by CHC are non-operational at this time:

We are actively working to find solutions to replace the services handled by CHC. In the meantime, Alliant Health Plans has temporary solutions for claims, electronic remittance and eligibility as described below:
