I want to find all diagnoses related to the circulatory system (ICD-9 codes 390-459) with a specificity scale of 0, any timing, and a panel accuracy scale of 100. This query is designed to identify patients with any diagnosis related to the circulatory system, including conditions such as hypertension, coronary heart disease, and cerebrovascular diseases, with the highest level of accuracy.
