I want to find all instances of cord blood stem cell transplant procedures in the inpatient ICD9 (International Classification of Diseases, 9th Revision) dataset, specifically within the category of operations on the hemic and lymphatic system, operations on bone marrow and spleen, and bone marrow or hematopoietic stem cell transplants. The query will be applied to any time period, with a specificity scale of 0, and the panel's accuracy scale will be set to 100. The query will be inverted, with only one item occurrence required for the search.
