(b) An administrator subcontractor may meet the requirements of this section by entering into a written agreement with the administrator contractor only, provided the written agreement meets the requirements of the Insurance Code Chapter 4151 and this section, as applicable. (c) A written agreement entered into under this section may not be construed to limit, in any way, an insurer's ultimate accountability and responsibility for compliance with all statutory and regulatory requirements under the Insurance Code, the Labor Code, and rules adopted thereunder. (d) A written agreement entered into under this section shall include: (1) a requirement that the administrator must comply with all statutory, contractual, and regulatory requirements related to a function assumed or carried out by the administrator and related to a plan for which the administrator performs or offers to perform administrative services; (2) a description of the administrative services the administrator is expected to provide and any applicable instructions related to the performance of those services, including references to an insurer's claims handling practices or procedures; (3) a provision relating to the continuity of services and addressing the obligations of the administrator and the insurer under §7.1615 of this subchapter (relating to Transfer of Books and Records), including the method and manner in which the insurer and administrator will meet those requirements; and (4) a provision addressing an insurer's obligation to review and audit the performance of its administrators under §7.1611 of this subchapter (relating to Operational Review and On-Site Audit), including the method and manner in which the insurer will meet those requirements.
