I want to find all patients with a diagnosis of cerebrovascular diseases (ICD codes I60-I69) in the ICD10_ICD9 field within the Diagnoses section of the data. The query should have a specificity scale of 0, meaning that it will include all possible matches, and the timing should be set to ANY, meaning that it will include diagnoses from any point in time. The panel number is 1, the accuracy scale is set to 100, indicating high accuracy, and the panel timing is also set to ANY. The query is not inverted, and it will return a total of 1 item. The class of the item is ENC, which stands for Encounter.
