CMS has issued a proposed rule that would establish ACA Marketplace health plan payment parameters and essential benefit standards for 2016. Specifically, the wide-ranging proposed rule addresses, among other things: the risk adjustment, reinsurance, and risk corridors programs; cost sharing parameters; user fees for federally-facilitated exchanges; standards for qualified health plans, including network adequacy and quality improvement; the Small Business Health Options Program; guaranteed availability and renewability, rate review; the medical loss ratio program; and minimum essential health benefits (including new policies and procedures for enrollee requests for prescription drugs not included on a plan’s formulary).  CMS will accept comments on the proposed rule until December 22, 2014.
