Even before passage of the Affordable Care Act (ACA), group health plan sponsors and administrators faced a significant array of notice and disclosure obligations. Those obligations have only increased with passage of the ACA, and in many cases existing disclosure requirements have been revised. For this reason, we are providing a table summarizing the principal notice and disclosure obligations currently applicable to group health plans, including those required under the ACA. The first part of the table summarizes disclosure rules applicable to all welfare benefit plans, and the second part focuses on rules applicable specifically to group health plans. The table also indicates who must receive each disclosure, and when it must be provided.
