The main purpose of the Ensuring Child Health Coverage Compensation in Divorce Act of 2026 is to improve access to health insurance benefits for children whose parents are separated or divorced. The legislation aims to ensure that custodial parents can effectively manage their children's health care needs by streamlining the process for accessing benefits under medical child support orders. Key provisions of the legislation require group health plans, health insurance issuers, and Federal Employees Health Benefits Program plans to provide specific support to custodial parents.
