UnitedHealth Group is vigorously defending its proposed $13 billion acquisition of Change Healthcare by arguing a Justice Department lawsuit to block the deal presents theories with "no basis in fact and law" about how competition could be harmed.
The Minnetonka-based health care giant on Thursday called the lawsuit "flawed" in a statement issued shortly after a federal judge scheduled a 12-day trial of the case for August.
It was UnitedHealth Group's fullest public response to the litigation thus far, echoing themes from a recent court filing where the company called the Justice Department's theories "vague and speculative."
The department declined to comment Thursday.
UnitedHealth Group runs UnitedHealthcare, which is the nation's largest health insurer. Tennessee-based Change Healthcare would add to UnitedHealth Group's already influential unit for health care data and technology within Optum, a division that provides a variety of health care services.
"The government's case rests entirely on speculation and theories unsupported by any past conduct, i.e. that Optum will somehow exploit Change Healthcare's products and services to secure an unfair advantage for UnitedHealthcare's health insurance business," the company said.
In February, the Justice Department filed a civil lawsuit in the U.S. District Court for the District of Columbia to stop the acquisition, which it said was anticompetitive. Putting Change Healthcare's technology into the hands of UnitedHealth Group could lower the quality of health insurance, the government alleged, and make coverage more costly for millions of people.
The department said UnitedHealth Group is a "behemoth" that would gain too much power through the acquisition in the world of electronic data transactions between insurance companies and health care providers.
