Section R9-22-712.69 - DRG Reimbursement: Covered Day Adjusted DRG Base Payment and Covered Day Adjusted Outlier Add-on Payment
Current through Register Vol. 30, No. 38, September 20, 2024
Adjustments to the payments are made to account for days not covered by AHCCCS as follows:
1. A covered day reduction factor unadjusted is determined if the member is not eligible on the first day of the inpatient stay but is eligible for subsequent days during the inpatient stay. In this case, a covered day reduction factor unadjusted is calculated by dividing the number of AHCCCS covered days by the DRG National Average length of stay. The number of AHCCCS covered days is equal to the number of days the member is eligible during inpatient stay.
2. A covered day reduction factor unadjusted is also determined if the member is eligible on the first day of the inpatient stay but is determined ineligible for one or more days prior to the date of discharge. In this case, a covered day reduction factor unadjusted is calculated by adding one to the number of AHCCCS covered days and dividing the result by the DRG National Average length of stay. The number of AHCCCS covered days is equal to the number of days the member is eligible during the inpatient stay.
3. If the covered day reduction factor unadjusted is greater than one, then the covered day reduction factor final is one; otherwise, the covered day reduction factor final is equal to the covered day reduction factor unadjusted.
4. The covered day adjusted DRG base payment is an amount equal to the product of the unadjusted DRG base payment and the covered day reduction factor final.
5. The covered day adjusted DRG outlier add-on payment is an amount equal to the product of the unadjusted DRG outlier add-on payment and the covered day reduction factor final.
