OPPS rate.

(1) The medicaid agency calculates hospital-specific outpatient prospective payment system (OPPS) rates using all of the following:
(a) A base conversion factor established by the agency;
(b) An adjustment for direct graduate medical education (DGME); and
(c) The latest wage index information established and published by the centers for medicare and medicaid services (CMS) when the OPPS rates are set for the upcoming year. Wage index information reflects labor costs in the cost-based statistical area (CBSA) where a hospital is located.
(2) Base conversion factors. The agency calculates the base enhanced ambulatory patient group (EAPG) conversion factor during a hospital payment system rebasing. The base is calculated as the maximum amount that can be used, along with all other payment factors and adjustments described in this chapter, to maintain aggregate payments across the system. The agency will publish base conversion factors on its website.
(3) Wage index adjustments reflect labor costs in the CBSA where a hospital is located.
(a) The agency determines the labor portion of the base rate by multiplying the base rate by the labor factor established by medicare; then
(b) Multiplying the amount in (a) of this subsection is multiplied by the most recent wage index information published by CMS when the rates are set; then
(c) The agency adds the nonlabor portion of the base rate to the amount in (b) of this subsection to produce a hospital-specific wage adjusted factor.
(4) DGME. The agency obtains the DGME information from the hospital's most recently filed medicare cost report as available in the CMS health care cost report information system (HCRIS) dataset.
(a) The hospital's medicare cost report must cover a period of twelve consecutive months in its medicare cost report year.
(b) If a hospital's medicare cost report is not available on HCRIS, the agency may use the CMS Form 2552-10 to calculate DGME.
(c) In the case where a hospital has not submitted a CMS medicare cost report in more than eighteen months from the end of the hospital's cost reporting period, the agency may remove the hospital's DGME adjustment.
(d) The agency calculates the hospital-specific DGME by dividing the DGME cost reported on worksheet B, part 1 of the CMS cost report by the adjusted total costs from the CMS cost report.
(5) The formula for calculating the hospital's final specific conversion factor is:
EAPG base rate × (.6(wage index) + .4)/(1-DGME)
