I want to find patients with a diagnosis of external causes of morbidity (v0-y9) and specifically those who have experienced assault (x92-y08), including assault by blunt object (y00) or assault by crashing of a motor vehicle (y03). This query is designed to identify patients with these specific diagnoses using the ICD10_ICD9 coding system. The accuracy scale is set to 100, indicating a high level of precision, and the timing is set to ANY, meaning that the diagnosis could have occurred at any point in time. The panel's specificity scale is set to 0, indicating that all cases meeting the criteria will be included in the results.
