Led by New York Attorney General Andrew Cuomo, a phalanx of interests charged Minnetonka-based UnitedHealth and its Ingenix division with denying millions of dollars in claims for millions of Americans when they use doctors outside of their insurer's network.
Cuomo said Wednesday that he plans to sue UnitedHealth, launch an industrywide investigation into billing procedures and seek unspecified restitution for consumers. He has sent subpoenas to 16 insurers -- including the nation's five largest insurers -- that use Ingenix data to determine how rates are computed.
"This is an industrywide investigation because we believe this is an industrywide scheme to deceive and defraud consumers," Cuomo said in a New York press conference. "Ingenix is at the center of this."
UnitedHealth said it intends to "cooperate fully" in Cuomo's inquiry, but it defended Ingenix and its ability to analyze 1.3 billion fresh records of actual doctors' charges to determine a range of costs for medical procedures.
"It gives the health care marketplace a snapshot of the average cost for a given service in a given area," said spokesman Don Nathan.
Cuomo's announcement came as UnitedHealth Group, the nation's largest insurer, already was off to a rocky start with regulators in 2008. A UnitedHealth subsidiary was fined $3.5 million in California last month over problems involving the handling of medical-treatment claims, with more fines possible.
Ingenix is a $1.65 billion arm of UnitedHealth that collects, sorts and analyzes a large array of data, including therapeutic outcomes and billing information.
At the heart of Cuomo's assertion that consumers are short-shrifted by Ingenix is the common health insurance term "reasonable and customary." The term is used to describe a typical cost for treatment of a condition.
