DRG high outliers.

(1) The medicaid agency identifies a diagnosis-related group (DRG) high outlier claim based on the claim's estimated costs. The agency allows a high outlier payment for claims paid using the DRG payment method when high outlier criteria are met.
(a) To qualify as a DRG high outlier claim, the estimated costs for the claim must be greater than the outlier threshold effective for the date of admission. The outlier threshold amount is depicted in the following table:
Dates of Admission
Pediatric
Nonpediatric
February 1, 2011 - July 31, 2012
 
Base DRG * 1.50
 
Base DRG * 1.75
August 1, 2012 - June 30, 2013
 
Base DRG * 1.429
 
Base DRG * 1.667
July 1, 2013 - June 30, 2014
 
Base DRG * 1.563
 
Base DRG * 1.823
July 1, 2014, and after
 
Base DRG + $40,000
 
Base DRG + $40,000
(b) The agency calculates the estimated costs of the claim by multiplying the total submitted charges, minus the nonallowed charges on the claim, by the hospital's ratio of costs-to-charges (RCC).
(c) When a transferring hospital submits a transfer claim to the agency, the high outlier criteria used to determine whether the claim qualifies for high outlier payment is the prorated DRG amount for the claim before the transfer payment.
(2) The agency calculates the high outlier payment by multiplying the hospital's estimated cost above threshold (CAT) by the outlier adjustment factor. The outlier adjustment factors, which vary by dates of admission and inpatient payment policy, are depicted in the table at the end of this subsection.
(a) For inpatient claims paid under the all-patient-diagnosis-related group (AP-DRG), the agency uses a separate outlier adjustment factor for:
(i) Pediatric services, including all claims submitted by children-specialty hospitals;
(ii) Burn services; and
(iii) Nonpediatric services.
(b) For inpatient claims paid under the all-patient refined-DRG (APR-DRG), the agency uses a separate outlier adjustment factor for a:
(i) Severity of illness (SOI) of one or two; or
(ii) SOI of three or four.

(3) For state-administered programs (SAP), the agency applies the hospital-specific ratable to the outlier adjustment factor.

(5) When directed by the legislature to achieve targeted expenditure levels, as described in WAC 182-550-3000(8), the agency may apply an inpatient adjustment factor to any of the high outlier thresholds and to any of the outlier adjustment factors described in this section.
(6) The agency applies the following to the payment for each claim:
(a) All applicable adjustments for client responsibility;
(b) Any third-party liability;
(c) Medicare payments; and
(d) Any other adjustments as determined by the agency.
