(a) The room and board component of the rates to be paid by the state to private facilities and facilities operated by regional education service centers which are licensed to provide residential care pursuant to § 17a-227, but not certified to participate in the Title XIX Medicaid program as intermediate care facilities for individuals with intellectual disabilities, shall be determined annually by the Commissioner of Social Services, except that rates effective April 30, 1989, shall remain in effect through October 31, 1989. Any facility with real property other than land placed in service prior to July 1, 1991, shall, for the fiscal year ending June 30, 1995, receive a rate of return on real property equal to the average of the rates of return applied to real property other than land placed in service for the five years preceding July 1, 1993. For the fiscal year ending June 30, 1996, and any succeeding fiscal year, the rate of return on real property for property items shall be revised every five years. The commissioner shall, upon submission of a request by such facility, allow actual debt service, comprised of principal and interest, on the loan or loans in lieu of property costs allowed pursuant to § 17-313b-5 of the regulations of Connecticut state agencies, whether actual debt service is higher or lower than such allowed property costs, provided such debt service terms and amounts are reasonable in relation to the useful life and the base value of the property. In the case of facilities financed through the Connecticut Housing Finance Authority, the commissioner shall allow actual debt service, comprised of principal, interest and a reasonable repair and replacement reserve on the loan or loans in lieu of property costs allowed pursuant to § 17-313b-5 of the regulations of Connecticut state agencies, whether actual debt service is higher or lower than such allowed property costs, provided such debt service terms and amounts are determined by the commissioner at the time the loan is entered into to be reasonable in relation to the useful life and base value of the property. The commissioner may allow fees associated with mortgage refinancing provided such refinancing will result in state reimbursement savings, after comparing costs over the terms of the existing proposed loans. For the fiscal year ending June 30, 1992, the inflation factor used to determine rates shall be one-half of the gross national product percentage increase for the period between the midpoint of the cost year through the midpoint of the rate year. For fiscal year ending June 30, 1993, the inflation factor used to determine rates shall be two-thirds of the gross national product percentage increase from the midpoint of the cost year to the midpoint of the rate year. For the fiscal years ending June 30, 1996, and June 30, 1997, no inflation factor shall be applied in determining rates. The Commissioner of Social Services shall prescribe uniform forms on which such facilities shall report their costs. Such rates shall be determined on the basis of a reasonable payment for necessary services. Any increase in grants, gifts, fund-raising or endowment income used for the payment of operating costs by a private facility in the fiscal year ending June 30, 1992, shall be excluded by the commissioner from the income of the facility in determining the rates to be paid to the facility for the fiscal year ending June 30, 1993, provided any operating costs funded by such increase shall not obligate the state to increase expenditures in subsequent fiscal years. Nothing contained in this section shall authorize a payment by the state to any such facility in excess of the charges made by the facility for comparable services to the general public. The service component of the rates to be paid by the state to private facilities and facilities operated by regional education service centers which are licensed to provide residential care pursuant to § 17a-227, but not certified to participate in the Title XIX Medicaid programs as intermediate care facilities for individuals with intellectual disabilities, shall be determined annually by the Commissioner of Developmental Services in accordance with § 17b-244a. For the fiscal year ending June 30, 2008, no facility shall receive a rate that is more than two per cent greater than the rate in effect for the facility on June 30, 2007, except any facility that would have been issued a lower rate effective July 1, 2007, due to interim rate status or agreement with the department, shall be issued such lower rate effective July 1, 2007. For the fiscal year ending June 30, 2009, no facility shall receive a rate that is more than two per cent greater than the rate in effect for the facility on June 30, 2008, except any facility that would have been issued a lower rate effective July 1, 2008, due to interim rate status or agreement with the department, shall be issued such lower rate effective July 1, 2008. For the fiscal years ending June 30, 2010, and June 30, 2011, rates in effect for the period ending June 30, 2009, shall remain in effect until June 30, 2011, except that (1) the rate paid to a facility may be higher than the rate paid to the facility for the period ending June 30, 2009, if a capital improvement required by the Commissioner of Developmental Services for the health or safety of the residents was made to the facility during the fiscal years ending June 30, 2010, or June 30, 2011, and (2) any facility that would have been issued a lower rate for the fiscal year ending June 30, 2010, or June 30, 2011, due to interim rate status or agreement with the department, shall be issued such lower rate. For the fiscal year ending June 30, 2012, rates in effect for the period ending June 30, 2011, shall remain in effect until June 30, 2012, except that (A) the rate paid to a facility may be higher than the rate paid to the facility for the period ending June 30, 2011, if a capital improvement required by the Commissioner of Developmental Services for the health or safety of the residents was made to the facility during the fiscal year ending June 30, 2012, and (B) any facility that would have been issued a lower rate for the fiscal year ending June 30, 2012, due to interim rate status or agreement with the department, shall be issued such lower rate. Any facility that has a significant decrease in land and building costs shall receive a reduced rate to reflect such decrease in land and building costs. The rate paid to a facility may be increased if a capital improvement approved by the Department of Developmental Services, in consultation with the Department of Social Services, for the health or safety of the residents was made to the facility during the fiscal year ending June 30, 2014, or June 30, 2015, only to the extent such increases are within available appropriations. For the fiscal years ending June 30, 2016, and June 30, 2017, rates shall not exceed those in effect for the period ending June 30, 2015, except the rate paid to a facility may be higher than the rate paid to the facility for the period ending June 30, 2015, if a capital improvement approved by the Department of Developmental Services, in consultation with the Department of Social Services, for the health or safety of the residents was made to the facility during the fiscal year ending June 30, 2016, or June 30, 2017, to the extent such rate increases are within available appropriations. For the fiscal years ending June 30, 2016, and June 30, 2017, and each succeeding fiscal year, any facility that would have been issued a lower rate, due to interim rate status, a change in allowable fair rent or agreement with the department, shall be issued such lower rate. For the fiscal years ending June 30, 2018, and June 30, 2019, rates shall not exceed those in effect for the period ending June 30, 2017, except the rate paid to a facility may be higher than the rate paid to the facility for the period ending June 30, 2017, if a capital improvement approved by the Department of Developmental Services, in consultation with the Department of Social Services, for the health or safety of the residents was made to the facility during the fiscal year ending June 30, 2018, or June 30, 2019, to the extent such rate increases are within available appropriations. For the fiscal years ending June 30, 2020, and June 30, 2021, rates shall not exceed those in effect for the fiscal year ending June 30, 2019, except the rate paid to a facility may be higher than the rate paid to the facility for the fiscal year ending June 30, 2019, if a capital improvement approved by the Department of Developmental Services, in consultation with the Department of Social Services, for the health or safety of the residents was made to the facility during the fiscal year ending June 30, 2020, or June 30, 2021, to the extent such rate increases are within available appropriations. For the fiscal years ending June 30, 2022, and June 30, 2023, rates shall be based upon rates in effect for the fiscal year ending June 30, 2021, inflated by the gross domestic product deflator applicable to each rate year, except the commissioner may, in the commissioner’s discretion and within available appropriations, provide pro rata fair rent increases to facilities which have documented fair rent additions placed in service in the cost report years ending September 30, 2020, and September 30, 2021, that are not otherwise included in rates issued, or if a rate adjustment for a capital improvement approved by the Department of Developmental Services, in consultation with the Department of Social Services, for the health or safety of the residents was made to the facility during the fiscal year ending June 30, 2022, or June 30, 2023.

(b) Notwithstanding the provisions of subsection (a) of this section, state rates of payment for the fiscal years ending June 30, 2018, June 30, 2019, June 30, 2020, and June 30, 2021, for residential care homes and community living arrangements that receive the flat rate for residential services under § 17-311-54 of the regulations of Connecticut state agencies shall be set in accordance with section 298 of public act 19-117*. For the fiscal years ending June 30, 2022, and June 30, 2023, rates shall be based upon rates in effect for the fiscal year ending June 30, 2021, inflated by the gross domestic product deflator applicable to each rate year.

(c) The Commissioner of Social Services and the Commissioner of Developmental Services shall adopt regulations in accordance with the provisions of chapter 54 to implement the provisions of this section.
