851.96 — Other and unspecified cerebral laceration and contusion, with open intracranial wound, with loss of consciousness of unspecified duration

851.96 is an ICD-9-CM diagnosis code for other and unspecified cerebral laceration and contusion, with open intracranial wound, with loss of consciousness of unspecified duration. 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 S01.90XA (Unspecified open wound of unspecified part of head, initial encounter) and S06.339A (Contusion and laceration of cerebrum, unspecified, with loss of consciousness of unspecified duration, 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.
