I want to find all patients who have been diagnosed with Diabetes Mellitus at any point in time, with a high level of specificity (1000%) and accuracy, and the query should not be inverted. The panel should include only one item, which is the diagnosis of Diabetes Mellitus under the category of Endocrine disorders, specifically Other endocrine gland diseases, with the item key being \i2b2_DIAG\i2b2\Diagnoses\Endocrine disorders (240-259)\Other endocrine gland diseases (250-259)\(250) Diabetes mellitus. The icon for this item is FA, and it is not a synonym.
