When people go to the emergency room, they are often stunned to discover that doctors who treated them are not employed by the hospital and bill their insurance company separately. These doctors negotiate separate deals with insurance companies for payment. If the doctor and the insurance company never strike a deal, the visit is billed at much higher out-of-network rates. While the insurance company sometimes pays the higher amount, unlucky patients like Mr. Moore can be caught in the crossfire. They receive care and have no idea what it will end up costing them.
New research published in The New England Journal of Medicine on Wednesday found that more than one in five patients visiting the emergency room may face the same financial shock.
