Glossary Definition

Last Updated: 2007-09-26


Patients were classified into a major diagnostic group depending on the most responsible diagnosis, that is, the one that contributed the most to the patients stay in hospital. Diagnostic groups are organized by body systems, for example, musculoskeletal, circulatory, and so on. Surgical patients were additionally categorized into a major procedure group, also organized by body system. A patient was determined to have a cognitive impairment if there was a relevant ICD-9-CM code in any of the 16 diagnosis fields. These were: 290.0-290.9, 294.0, 294.1, 294.8, 294.9, 291.1, 291.2, 292.82, 292.83, 331.0, 331.1, 331.3, 331.7, 331.9, 797, and 799.3.
