The Medical Information Bureau (MIB) is a nonprofit trade association with approximately 700 life insurance companies as members in the United States and Canada. A computer bank that contains primarily medical information is maintained by the MIB. Safeguards are taken to assure confidentiality, and there is no linkage with other computer banks. Information is submitted to the MIB only after the individuals involved give authorization, and they have access to their records and can make corrections if necessary. Dissemination of computer information is made only to member companies when they have a bona fide application or claim and then only with the consent of the person involved. Medical directors of member companies have the primary responsibility for maintaining integrity and seeing that their companies adhere to the rules of the MIB.
