Stanford Health Care and its physicians are in-network with out of state Blue Cross/Blue Shield plans, as long as the plan uses the nationwide network of providers. This is known as the Blue Card network. Most employer sponsored group plans will include this network, especially if they have employees located in multiple states. Please contact your health plan or your employer to inquire about access to this network.
