This bill mandates the Secretary of Veterans Affairs to temporarily extend the claim filing period for medical care under the CHAMPVA program for specific individuals. This extension applies to "covered individuals" who are eligible for CHAMPVA medical care and also entitled to hospital insurance benefits under Medicare Part A. During the period from the bill's enactment until September 30, 2027 , if a covered individual receives retroactive approval for medical care, their claim filing period will commence on the date they receive notice of such approval. This period will then extend for not less than 365 days from that notice date. The Secretary is also directed to prescribe regulations to implement these provisions.
