“The Labor Department opposes a health insurance practice called ‘cross-plan offsetting,’ in which insurers like UnitedHealth reduce payments owed to medical providers for services rendered to specific patients. The reductions are meant to offset overpayments the providers previously received on account of different patients who participate in other plans insured by the same company. This practice violates [ERISA], the DOL said in a brief filed Sept. 5 in the U.S. Court of Appeals for the Eighth Circuit.” [Bloomberg BNA]
