UnitedHealth Group says it is cooperating with federal criminal and civil investigations involving its market-leading Medicare business. The health care giant said Thursday that it had contacted the Department of Justice after reviewing media reports about investigations into certain elements of its business. The Wall Street Journal has been reporting that federal officials had launched investigations into how the company records diagnoses that lead to extra payments for its Medicare Advantage plans. Those are privately run versions of the government’s Medicare coverage program mostly for people ages 65 and over. UnitedHealth runs the nation’s largest Medicare Advantage business.
