About ICD-9-CM 46.40
46.40 is an ICD-9-CM procedure code for revision of intestinal stoma, not otherwise specified. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-PCS took over.
The CMS General Equivalence Mappings translate it to 2 ICD-10-PCS codes, such as 0WBFXZ2 (Excision of Abdominal Wall, Stoma, External Approach) and 0WQFXZ2 (Repair Abdominal Wall, Stoma, External Approach). All of these are approximate matches, so review the record to pick the right one.
