852.59 — Extradural hemorrhage following injury with open intracranial wound, with concussion, unspecified

852.59 is an ICD-9-CM diagnosis code for extradural hemorrhage following injury with open intracranial wound, with concussion, unspecified. 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 3 ICD-10-CM codes, such as S01.90XA (Unspecified open wound of unspecified part of head, initial encounter), S06.4X0A (Epidural hemorrhage without loss of consciousness, initial encounter) and S06.4X9A (Epidural hemorrhage 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.
