I want to find all instances where Defibrination syndrome was listed as an Admit Diagnosis, with no specificity scale applied, and the query timing and panel timing set to ANY. The specificity scale is set to 0, meaning all occurrences of the diagnosis will be included, and the panel accuracy scale is set to 100, indicating a high level of confidence in the results. The query is focused on the hlevel 4 item, which is the specific code for Defibrination syndrome within the broader category of Hematologic diseases and Coagulation defects.
