An ERISA class action suit has been filed against Cigna Health and Life Insurance Co. in Connecticut District Court, alleging the insurer is overcharging for medical services.

Arizona citizen Aubrey Srednicki, the named plaintiff, has a healthcare plan that claims Cigna negotiates lower rates with in-network providers to help those insured with Cigna save money, the complaint said. However, the plaintiffs allege that Cigna has participated in a "fraudulent scheme," that the proposed class members did not save money, and that they were overcharged for medical services.

The complaint lays out an example in which Srednicki obtained a blood test from an in-network provider, LabCorp, and allegedly discovered the uninsured cash price was significantly less than what she paid. On the Explanation of Benefits, Cigna allegedly said the provider was "HLTH DIAG LAB" instead of the actual provider LabCorp, and the amount billed was $17,462.66.
