Newly acquired facilities shall receive an interim per diem rate of payment for each level of care based on the existing rate adjusted to reflect any changes in property values pursuant to section 17-311-57(1). In the event that substantive changes in operation have been affected by the new owners materially changing operating costs, additional adjustments to the existing rates may be made to the extent such changes in operations and related costs are specifically identified and documented by the facility.
An interim per diem rate may be authorized for a facility which has undergone changes in level of care or significant changes in licensed bed capacity mandated or approved by the department of health services and the commission on hospitals and health care.
An interim per diem rate may be revised by the commissioner at any time based on additional information which may become available to him. The interim rate shall remain in effect until the first of the following occurs:
Interim rates shall be replaced by revised per diem rates computed on the basis of actual costs which are allowable as defined in these regulations, and minimum allowable patient days (ninety percent utilization except as provided in section 17-311-52(15) for the period in which the interim rates were in effect. Proper retroactive adjustments, in favor of the provider or the state, shall be made to all amounts paid on the basis of interim rates.
