Rates are adjusted by age, gender, age-gender interactions, and APR-DRG risk of mortality score. When reporting is by age, the adjustment is by gender and APR-DRG risk of mortality score; when reporting is by gender, the adjustment is by age and APR-DRG risk of mortality score. See Guide to Inpatient Quality Indicators at http://qualityindicators.ahrq.gov for a discussion of this measure, including a complete list of ICD-9-CM codes.
