Connecticut-based managed care provider Aetna Life Insurance Co. has been slapped with 21 lawsuits over the course of a week in a New Jersey federal court accusing it of failing to fund reconstructive surgery for breast cancer patients who’ve had mastectomies.

The crop of suits follows a ruling from the U.S. Court of Appeals for the Third Circuit reversing a decision that said such claims are preempted under the Employee Retirement Income Security Act, or ERISA.
