Michigan sues Blue Cross Blue Shield of Michigan over alleged illegal insurance monopoly
Lawsuit filed
The state of Michigan, through Attorney General Dana Nessel, sued Blue Cross Blue Shield of Michigan, alleging the insurer has obtained an illegal monopoly through illegal and anti-competitive agreements with other Blue Cross Blue Shield entities. The complaint alleges the company used its market power to inflate premiums and out-of-pocket costs while cutting payments to health care providers near the lowest in the nation, with Blue Cross allegedly controlling 65 percent of the state health insurance market and 79 percent of the PPO market.
