I want to find all instances of "Diabetes mellitus" as a diagnosis in the Endocrine disorders section of the ICD-9-CM coding system, specifically under the subcategory of Other endocrine gland diseases, with a specificity scale of 0 and a panel accuracy scale of 100, where the query timing and panel timing are set to ANY. The query is named "Diabetes mellitus" and is the first panel in the query definition.
