State licensing rules set the minimum requirements for Medicaid providers. The Medicaid program may set more stringent standards if desired, however. For example, some states allow facilities to offer rooms shared by two, three, or more residents. But since one of the purposes of assisted living is to foster independence and autonomy, some state Medicaid programs will only contract with facilities that offer private occupancy unless the resident chooses to share a room/unit. Some states also require facilities contracting with Medicaid to offer apartment-style units rather than bedrooms. (These include Oregon, Washington, and North Dakota.) Further, if licensing rules do not include sufficient requirements for facilities serving people with Alzheimer's disease, the Medicaid contracting requirements may specify additional training or other requirements.
