The main purpose of this legislation, known as the "No Medicare Clawbacks Act of 2026," is to protect individuals who are enrolled in both Medicare and a group health plan from having payments recouped or "clawed back" by their health plan under certain conditions. This aims to provide financial security and clarity for those who may be affected by overlapping health coverage. Key provisions of the law include a specific prohibition against group health plans recouping payments for medical services if certain criteria are met.
