In 2011, Allman went public about his battle with hepatitis C. He headlined Merck and the American Liver Foundation's "Tune In to Hep C Campaign" to raise awareness and urge baby boomers to get tested and treated. As part of Tune In to Hep C, The Allman Brothers Band headlined a hepatitis C fundraiser and awareness concert at the Beacon Theater in New York. The concert raised $250,000 to benefit the National Viral Hepatitis Roundtable and the American Liver Foundation for education and awareness efforts. The National Viral Hepatitis Roundtable in October 2017 created the Gregg Allman Hepatitis C Leadership Award – an annual award to posthumously honor Allman and others who work on behalf of people living with hepatitis C. Michael Lehman, Allman's longtime manager, accepted the award on his behalf.
