(a) Subject to Section 5G-45, beginning July 1, 2014, an annual assessment on health care services is imposed on each supportive living facility in an amount equal to $2.30 multiplied by the supportive living facility’s care days. This assessment shall not be billed or passed on to any resident of a supportive living facility.
     (b) Nothing in this Section shall be construed to authorize any home rule unit or other unit of local government to license for revenue or impose a tax or assessment upon supportive living facilities or the occupation of operating a supportive living facility, or a tax or assessment measured by the income or earnings or care days of a supportive living facility.
     (c) The assessment imposed by this Section shall not be due and payable, however, until after the Department notifies the supportive living facilities, in writing, that the payment methodologies to supportive living facilities required under Section 5-5.01a of this Code have been approved by the Centers for Medicare and Medicaid Services of the U.S. Department of Health and Human Services and the waivers under 42 C.F.R. § 433.68 for the assessment imposed by this Section, if necessary, have been granted by the Centers for Medicare and Medicaid Services of the U.S. Department of Health and Human Services.
