I want to find all inpatient procedures related to operations on the ear, as recorded in the ICD9 (International Classification of Diseases, 9th Revision) medical coding system, within a specific time frame (ANY). The query will have a specificity scale of 0 and an accuracy scale of 100, indicating that the results should be highly accurate and not limited by specificity. The panel will include only one item, which is focused on operations on the ear, and the query will not be inverted. The query will retrieve data from the i2b2 cell repository, specifically from the Procedures category, under the ICD9 (Inpatient) section, within the Operations on ear subcategory.
