(1) For inpatient hospital services rendered, or if applicable, for inpatient hospital discharges occurring, on or after July 1, 1992 and on or before September 30, 1992, the Illinois Department shall reimburse hospitals for inpatient services under the reimbursement methodologies in effect for each hospital, and at the inpatient payment rate calculated for each hospital, as of June 30, 1992.

(2) For the purpose of calculating the inpatient payment rate for each hospital eligible to receive quarterly adjustment payments for targeted access and critical care, as defined by the Illinois Department on June 30, 1992, the adjustment payment for the period July 1, 1992 through September 30, 1992, shall be 25% of the annual adjustment payments calculated for each eligible hospital, as of June 30, 1992. The Illinois Department shall determine by rule the adjustment payments for targeted access and critical care beginning October 1, 1992.

The Illinois Department shall determine by rule the adjustment payments for uncompensated care beginning October 1, 1992.

(b) Inpatient payments. For inpatient services provided on or after October 1, 1993, in addition to rates paid for hospital inpatient services pursuant to the Illinois Health Finance Reform Act, as now or hereafter amended, or the Illinois Department's prospective reimbursement methodology, or any other methodology used by the Illinois Department for inpatient services, the Illinois Department shall make adjustment payments, in an amount calculated pursuant to the methodology described in paragraph (c) of this Section, to hospitals that the Illinois Department determines satisfy any one of the following requirements:

(1) Hospitals that are described in Section 1923 of the federal Social Security Act, as now or hereafter amended, except that for rate year 2015 and after a hospital described in Section 1923(b)(1)(B) of the federal Social Security Act and qualified for the payments described in subsection (c) of this Section for rate year 2014 provided the hospital continues to meet the description in Section 1923(b)(1)(B) in the current determination year; or

(2) Illinois hospitals that have a Medicaid inpatient utilization rate which is at least one-half a standard deviation above the mean Medicaid inpatient utilization rate for all hospitals in Illinois receiving Medicaid payments from the Illinois Department; or

(3) Illinois hospitals that on July 1, 1991 had a Medicaid inpatient utilization rate, as defined in paragraph (h) of this Section, that was at least the mean Medicaid inpatient utilization rate for all hospitals in Illinois receiving Medicaid payments from the Illinois Department and which were located in a planning area with one-third or fewer excess beds as determined by the Health Facilities and Services Review Board, and that, as of June 30, 1992, were located in a federally designated Health Manpower Shortage Area; or

(5) Any children's hospital, which means a hospital devoted exclusively to caring for children. A hospital which includes a facility devoted exclusively to caring for children shall be considered a children's hospital to the degree that the hospital's Medicaid care is provided to children if either (i) the facility devoted exclusively to caring for children is separately licensed as a hospital by a municipality prior to February 28, 2013; (ii) the hospital has been designated by the State as a Level III perinatal care facility, has a Medicaid Inpatient Utilization rate greater than 55% for the rate year 2003 disproportionate share determination, and has more than 10,000 qualified children days as defined by the Department in rulemaking; (iii) the hospital has been designated as a Perinatal Level III center by the State as of December 1, 2017, is a Pediatric Critical Care Center designated by the State as of December 1, 2017 and has a 2017 Medicaid inpatient utilization rate equal to or greater than 45%; or (iv) the hospital has been designated as a Perinatal Level II center by the State as of December 1, 2017, has a 2017 Medicaid Inpatient Utilization Rate greater than 70%, and has at least 10 pediatric beds as listed on the IDPH 2015 calendar year hospital profile; or

(2) hospitals with a Medicaid inpatient utilization rate that is equal to or greater than the mean Medicaid inpatient utilization rate but less than one standard deviation above the mean Medicaid inpatient utilization rate shall receive a per day adjustment payment equal to the sum of $25 plus $1 for each one percent that the hospital's Medicaid inpatient utilization rate exceeds the mean Medicaid inpatient utilization rate;

(3) hospitals with a Medicaid inpatient utilization rate that is equal to or greater than one standard deviation above the mean Medicaid inpatient utilization rate but less than 1.5 standard deviations above the mean Medicaid inpatient utilization rate shall receive a per day adjustment payment equal to the sum of $40 plus $7 for each one percent that the hospital's Medicaid inpatient utilization rate exceeds one standard deviation above the mean Medicaid inpatient utilization rate;

(4) hospitals with a Medicaid inpatient utilization rate that is equal to or greater than 1.5 standard deviations above the mean Medicaid inpatient utilization rate shall receive a per day adjustment payment equal to the sum of $90 plus $2 for each one percent that the hospital's Medicaid inpatient utilization rate exceeds 1.5 standard deviations above the mean Medicaid inpatient utilization rate; and

For purposes of this subsection, days of care funded by the U.S. Department of Veterans Affairs include authorized VA community care provided at non-VA hospitals.
