About ICD-9-CM E998.9

E998.9 is an ICD-9-CM diagnosis code for injury due to unspecified war operations but occurring after cessation of hostilities. 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 Y36.890A (Unspecified war operations occurring after cessation of hostilities, military personnel, initial encounter) and Y36.891A (Unspecified war operations occurring after cessation of hostilities, civilian, initial encounter). All of these are approximate matches, so review the record to pick the right one.
