An exchange run by a private sector company or nonprofit. Health plans and carriers in a private exchange must meet certain criteria defined by the exchange management. Private exchanges combine technology and human advocacy, include online eligibility verification, and mechanisms for allowing employers who connect their employees or retirees with exchanges to offer subsidies. They are designed to help consumers find plans personalized to their specific health conditions, preferred doctor/hospital networks, and budget. These exchanges are sometimes called marketplaces or intermediaries, and work directly with insurance carriers, effectively acting as an extension of the carrier.
