With 70 percent of grant funding for community health centers (CHCs) set to expire at the end of the month, Republicans continue their attempts to repeal the Affordable Care Act (ACA) with the catastrophic Graham-Cassidy proposal, threatening the health care of millions of Americans. The consequences of ignoring this funding cliff will be even more profound in light of the bill’s severe cuts to Medicaid, which makes up 46 percent of CHC revenues. By eliminating the ACA’s expansion of Medicaid and capping the traditional Medicaid program, Graham-Cassidy will jeopardize access to care for millions of Americans.

Every year, with support from the Department of Health and Human Services’ Health Resources and Services Administration, CHCs provide comprehensive and cost-effective primary health care to nearly 26 million patients—including over 330,000 veterans—in the nation’s most underserved communities, both urban and rural. Centers deliver over $24 billion in annual savings to America’s health care system, including $2,371 per Medicaid patient served in savings to the health care system, by providing primary and preventative care.

Community health centers are also economic engines in local communities: in 2014 alone, they generated over $45 billion in total economic activity and directly supported nearly 190,000 jobs. Funding for CHCs has garnished strong bipartisan support in the past, and failing to fund the program now will disrupt crucial care for new mothers, children, rural and underserved patients, and seniors.

Congress must fully fund CHCs to ensure continued access to affordable primary and preventative care. Republicans should cease their latest attempt to repeal the ACA, Graham-Cassidy, and instead work with Democrats to support effective programs like CHCs and stabilize the individual market. Congressional inaction will only force CHCs to close their doors, leaving millions of Americans without access to affordable services and many health care providers without jobs.
