I want to find patients admitted with a diagnosis of acute appendicitis or acute appendicitis with generalized peritonitis, using the ICD-9-CM code range K00-K94 for diseases of the digestive system and K35-K38 for diseases of the appendix, specifically K35 for acute appendicitis and K35.2 for acute appendicitis with generalized peritonitis. The query will be applied to any time period, and the specificity scale is set to 0. This query is part of a panel with panel number 1 and timing set to ANY, with an accuracy scale of 0 and the panel not being inverted. The items are not synonyms.
