This Frequently Asked Questions document explains the Home and Community Based Services (HCBS) Settings Rule, which was issued in 2014 by the Centers for Medicare and Medicaid Services (CMS) at the Department of Health and Human Services, and is a vital part of the broader effort to promote community integration for people with disabilities. The document includes descriptions of the rule and need for it, an explanation of its requirements, and details about application and compliance with the rule. The ACLU strongly supports implementation of the HCBS Settings Rule because it ensures people with disabilities have access to truly integrated alternatives to the regimentation and isolation of institutional life.
