A federal appeals court has reinstated an antitrust suit against the Blue Cross Blue Shield Association over claims that the group’s insurance providers conspired to decline coverage for a medical device company’s cardiac monitor.

A unanimous three-judge panel of the U.S. Court of Appeals for the Third Circuit determined in LifeWatch Services v. Highmark that LifeWatch Services had presented enough factual basis to proceed on claims against five insurance plan administrators, including WellPoint, Horizon Blue Cross Blue Shield of New Jersey and Highmark Inc., each of which uses the Blue Cross Blue Shield trademarks.
