About ICD-9-CM 863.39

863.39 is an ICD-9-CM diagnosis code for other injury to small intestine, with open wound into cavity. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.

The CMS General Equivalence Mappings translate it to 2 ICD-10-CM codes, such as S31.609A (Unspecified open wound of abdominal wall, unspecified quadrant with penetration into peritoneal cavity, initial encounter) and S36.408A (Unspecified injury of other part of small intestine, initial encounter). All of these are approximate matches, so review the record to pick the right one. Some mappings are combinations: more than one ICD-10 code is needed to fully express the ICD-9 code.
