This document contains a final regulation revising the minimum requirements for benefit claims procedures of employee benefit plans covered by Title I of the Employee Retirement Income Security Act of 1974 (ERISA or the Act). The regulation establishes new standards for the processing of claims under group health plans and plans providing disability benefits and further clarifies existing standards for all other employee benefit plans. The new standards are intended to ensure more timely benefit determinations, to improve access to information on which a benefit determination is made, and to assure that participants and beneficiaries will be afforded a full and fair review of denied claims. When effective, the regulation will affect participants and beneficiaries of employee benefit plans, employers who sponsor employee benefit plans, plan fiduciaries, and others who assist in the provision of plan benefits, such as third-party benefits administrators and health service providers or health maintenance organizations that provide benefits to participants and beneficiaries of employee benefit plans.
