ICD-9-CM diagnosis code (retired)
E999.0 — Late effect of injury due to war operations
About ICD-9-CM E999.0
E999.0 is an ICD-9-CM diagnosis code for late effect of injury due to war operations. 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 20 ICD-10-CM codes, such as Y36.010S (War operations involving explosion of depth-charge, military personnel, sequela), Y36.030S (War operations involving explosion of sea-based artillery shell, military personnel, sequela) and Y36.050S (War operations involving accidental detonation of onboard marine weapons, military personnel, sequela). All of these are approximate matches, so review the record to pick the right one.
