ICD-9-CM diagnosis code (retired)
863.95 — Injury to appendix, with open wound into cavity
About ICD-9-CM 863.95
863.95 is an ICD-9-CM diagnosis code for injury to appendix, 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 S36.899A (Unspecified injury of other intra-abdominal organs, 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.
