801.21 — Closed fracture of base of skull with subarachnoid, subdural, and extradural hemorrhage, with no loss of consciousness

801.21 is an ICD-9-CM diagnosis code for closed fracture of base of skull with subarachnoid, subdural, and extradural hemorrhage, with no 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 S02.109A (Fracture of base of skull, unspecified side, initial encounter for closed fracture), S06.4X0A (Epidural hemorrhage without loss of consciousness, initial encounter) and S06.5X0A (Traumatic subdural hemorrhage without loss of consciousness, 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.
