Cohn's writings have especially focused on social welfare and health care. He has been recognized in the pages of the Washington Post as "one of the nation's leading experts on health care policy" and in The New York Times as "one of the best health care writers out there".
From early 2009 through the spring of 2010, Cohn edited and was the primary writer for "The Treatment", a blog about health care for The New Republic. In May, 2010, he started a blog for "The New Republic" called "Citizen Cohn", a name he has kept for his Twitter feed.
Cohn is the author of a book, Sick: The Untold Story of America's Health Care Crisis - and the People Who Pay the Price (2007). In Sick, Cohn advocates for universal health insurance, financed by the government. It presents case studies that demonstrate how America's current system causes even many middle class Americans serious financial or medical hardship. It lays out a history of health insurance in America and points to the record of systems abroad, particularly in France.
Before joining The New Republic in 1997, Cohn served as executive editor at The American Prospect. Cohn has also written for the Boston Globe, Mother Jones, The New York Times, Newsweek, Rolling Stone, Slate and the Washington Post. He has been a media fellow at the Henry J. Kaiser Family Foundation. and a senior fellow at Demos, and is a member of the National Academy of Social Insurance. He has appeared on television and radio shows, including MSNBC's "Countdown," NPR's "Fresh Air," and "The Colbert Report".
In 2013, fellow health policy wonk Harold Pollack interviewed Cohn, getting his take on the future of the Affordable Care Act, the ACA's proposed Medicaid expansion, and the 2012 elections.
