801.23 — Closed fracture of base of skull with subarachnoid, subdural, and extradural hemorrhage, with moderate [1-24 hours] loss of consciousness

801.23 is an ICD-9-CM diagnosis code for closed fracture of base of skull with subarachnoid, subdural, and extradural hemorrhage, with moderate [1-24 hours] 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 7 ICD-10-CM codes, such as S02.109A (Fracture of base of skull, unspecified side, initial encounter for closed fracture), S06.4X3A (Epidural hemorrhage with loss of consciousness of 1 hour to 5 hours 59 minutes, initial encounter) and S06.4X4A (Epidural hemorrhage with loss of consciousness of 6 hours to 24 hours, 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.
