12VAC30-70-361. Base year standardized operating costs per case.

A. For the purposes of calculating the base year standardized operating costs per case, base year claims data for all DRG cases, including outlier cases, shall be used. Base year claims data for per diem cases shall not be used. Separate base year standardized operating costs per case shall be calculated for Type One and Type Two hospitals. In calculating the base year standardized operating costs per case, a transfer case shall be counted as a fraction of a case based on the ratio of its length of stay to the arithmetic mean length of stay for cases assigned to the same DRG as the transfer case.

B. Using the data elements identified in subsection E of 12VAC30-70-221, the following methodology shall be used to calculate the base year standardized operating costs per case:

1. The operating costs for each DRG case shall be calculated by multiplying the hospital's total charges for the case by the hospital's operating cost-to-charge ratio, as defined in subsection C of 12VAC30-70-221.

2. The standardized operating costs for each DRG case shall be calculated as follows:

a. The operating costs shall be multiplied by the statewide average labor portion of operating costs, yielding the labor portion of operating costs. Hence, the nonlabor portion of operating costs shall constitute one minus the statewide average labor portion of operating costs times the operating costs.

b. The labor portion of operating costs shall be divided by the hospital's Medicare wage index, yielding the standardized labor portion of operating costs.

c. The standardized labor portion of operating costs shall be added to the nonlabor portion of operating costs, yielding standardized operating costs.

3. The case-mix neutral standardized operating costs for each DRG case shall be calculated by dividing the standardized operating costs for the case by the hospital's case-mix index.

4. The base year standardized operating costs per case shall be calculated by summing the case-mix neutral standardized operating costs for all DRG cases and dividing by the total number of DRG cases.

5. The base year standardized operating costs per case shall be reduced by 5.1% to create a pool for outlier operating payments. Eligibility for outlier operating payments and the amount of the outlier operating payments shall be determined in accordance with 12VAC30-70-261.

C. Because the current cost report format does not separately identify psychiatric costs, claims data shall be used to calculate the base year standardized operating costs per case, as well as the base year standardized operating costs per day described in 12VAC30-70-321. At such time as the cost report permits the separate identification of psychiatric costs and the DRG payment system is recalibrated and rebased, cost report data shall be used to calculate the base year standardized operating costs per case and base year standardized operating costs per day.
