The Veterans' Caregiver Appeals Modernization Act of 2025 seeks to enhance the Department of Veterans Affairs' comprehensive assistance program for family caregivers of eligible veterans. A primary provision mandates the development and implementation of a single digital system for the Veterans Health Administration and the Board of Veterans' Appeals. This system will allow employees to access all applications and supporting documents related to caregiver assistance and appeals, streamlining the evaluation process. Furthermore, the bill clarifies that a family caregiver's eligibility for monthly personal caregiver stipends is not affected if an eligible veteran dies during the pendency of an appeal, provided the caregiver was entitled to such stipends based on evidence at the time of death. It also requires that Veterans Health Administration employees responsible for evaluating caregiver assistance appeals receive the same guidance and training as higher-level adjudicators for other veteran benefits. In developing these improvements, the Secretary of Veterans Affairs must consider lessons learned from existing digital systems and best practices for standardizing employee training.
