I want to find patients who have been diagnosed with migraine, unspecified, without mention of intractable migraine, and have also been diagnosed with anxiety disorder due to a general medical condition, with the specificity scale set to 0 and the accuracy scale set to 100. The timing for both panels is set to ANY, meaning the diagnoses can occur at any time. The query is named "Migrain-Anxiety@10:50:25."
