I want to find patients who have been diagnosed with Diabetes mellitus (e08-e13) at any time during their medical history, with a specificity scale of 0, accuracy scale of 100, and the panel number and timing set to ANY. This query is focused on endocrine, nutritional, and metabolic diseases and is based on the ICD10 and ICD9 coding systems.
