Section 17-1739-62 - Calculation of base prospective rates for psychiatric services(a) A base per diem rate for acute psychiatric inpatient services shall be established for all inpatient facilities using the following general methodology: (1) Deduct the capital related costs allocated to psychiatric services on the base year cost report;(2) Establish facility-specific ratios from claim charge data for psychiatric routine, special care, and ancillary charges and days to total routine, special care, and ancillary charges and days;(3) Multiply the ratios in paragraph (2) by total medicaid inpatient costs excluding capital related cost, and days for routine, special care, and ancillary services to achieve total psychiatric routine, special care, and ancillary medicaid inpatient costs and days as derived from the cost report; and(4) Total the resulting psychiatric costs and days for routine, special care, and ancillary services and achieve a facility-specific average medicaid psychiatric cost per day by dividing total psychiatric medicaid inpatient costs by total psychiatric inpatient medicaid days.(b) A psychiatric per diem rate ceiling which applies to all facilities statewide shall be calculated in the following manner: (1) Total the costs, excluding capital related costs, and days for all psychiatric services for all facilities, as identified in subsection (a);(2) Divide the total psychiatric inpatient costs calculated in paragraph (1) by total psychiatric inpatient days; and(3) Multiply the result of paragraph (2) by the statewide psychiatric ceiling factor (one hundred fifteen per cent) published annually by the department. This result shall be the statewide base year per diem rate ceiling for psychiatric services.(c) The prospective payment rate for psychiatric services for all facilities shall equal the lesser of either the facility-specific per diem rate or the per diem rate ceiling for inpatient psychiatric services.Haw.
