Contrary to the Social Security Act, St. Mary’s Regional Medical Center included 1,341 Medicare Part A paid days in the Medicaid fraction of its disproportionate share hospital (DSH) calculation.  As a result, we determined that its DSH reimbursement amount was overstated by $433,502.  Section 1886(d)(5)(F)(vi)(II) of the Social Security Act defines the Medicaid fraction of the DSH calculation as the fraction, the numerator of which is the number of patient days for which the patient was eligible for Medicaid but not entitled to benefits under Medicare Part A, and the denominator as the total number of patient days for the same period.  We recommend that St. Mary’s Regional Medical Center resubmit its FY 2002 Medicare cost report excluding the 1,341 Medicare Part A paid days from the Medicaid fraction and establish procedures to ensure that in the future only allowable days are included in the DSH reimbursement calculation.
