854.02 — Intracranial injury of other and unspecified nature without mention of open intracranial wound, with brief [less than one hour] loss of consciousness

854.02 is an ICD-9-CM diagnosis code for intracranial injury of other and unspecified nature without mention of open intracranial wound, with brief [less than one hour] loss of consciousness. 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 4 ICD-10-CM codes, such as S06.1X1A (Traumatic cerebral edema with loss of consciousness of 30 minutes or less, initial encounter), S06.1X2A (Traumatic cerebral edema with loss of consciousness of 31 minutes to 59 minutes, initial encounter) and S06.9X1A (Unspecified intracranial injury with loss of consciousness of 30 minutes or less, initial encounter). All of these are approximate matches, so review the record to pick the right one.
