The federal government will pay for disabled veterans now residing in assisted-living facilities, under a bill passed by Congress in December. But the measure doesn’t cover veterans who may move to such places in the future. Disabled veterans living at retirement homes, including those at Seacrest Retirement Center in West Haven, HighVue Manor in Hamden, and Mattatuck Health Care in Waterbury, were told in 2013 by the U.S. Department of Veterans Affairs that coverage of their housing was a mistake and would end. The coverage began in 2010. U.S. Rep. Rosa L. DeLauro obtained extensions for the Connecticut veterans who sought her help and she proposed the language in the bill approved that ensured their coverage would continue.
