On August 12, 2011, the Obama Administration made a series of announcements related to implement of Affordable Insurance Exchanges (Exchanges) under the Affordable Care Act (ACA). The Exchanges, which will become operational by January 1, 2014, are designed to provide competitive marketplaces for individuals and small employers to directly compare available private health insurance options on the basis of price, quality, and other factors. The Department of Health and Human Services (HHS) has issued a proposed rule addressing eligibility determinations for Exchange participation and insurance affordability programs, along with standards for employer participation in a new Small Business Health Options Program.  The official version of the rule will be published August 17, and comments will be accepted until October 31, 2011. HHS also released updated information on the status of state efforts to build Exchanges, and the Department provided information to governors on federal resources available to establish Exchanges.  In a related development, the Centers for Medicare & Medicaid Services (CMS) issued a proposed rule that would coordinate Exchange, Medicaid, and Children’s Health Insurance Program eligibility and enrollment. The CMS rule also addresses increased Federal Medical Assistance Percentage (FMAP) rates associated with medical assistance expenditures for certain “newly eligible” individuals. Comments will be accepted until October 31. Finally, the Internal Revenue Service (IRS) released regulations related to the ACA’s health insurance premium tax credit, which will help individuals purchase private health coverage through an Exchange.  Among other things, the proposed IRS regulations describe who will be eligible to receive the premium tax credit and how to compute the credit. The IRS also announces a November 17 public hearing on the regulation. The comment deadline is October 31.
