A Texas resident has filed a federal lawsuit against Bloomfield, Connecticut-based Cigna Health and Life Insurance Co. and one of its pharmacy benefit managers, CareCentrix Inc., charging they conspired to drive up the consumer costs of home patient care and durable medical equipment.

The suit, filed Oct. 6 by Jeffrey Neufeld in the U.S. District Court in Connecticut, accuses the companies of artificially inflating costs through a fraudulent billing scheme that required pharmacy benefit managers such as CareCentrix of Hartford to overcharge for co-payments and deductible and coinsurance payments. It alleges violations of the Racketeer Influenced and Corrupt Organizations and Employee Retirement Income Security acts. It does not specify the amount of damages sought, although Neufeld seeks to certify his case as a class action.
