800.63 — Open fracture of vault of skull with cerebral laceration and contusion, with moderate [1-24 hours] loss of consciousness

800.63 is an ICD-9-CM diagnosis code for open fracture of vault of skull with cerebral laceration and contusion, 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 3 ICD-10-CM codes, such as S02.0XXB (Fracture of vault of skull, initial encounter for open fracture), S06.333A (Contusion and laceration of cerebrum, unspecified, with loss of consciousness of 1 hour to 5 hours 59 minutes, initial encounter) and S06.334A (Contusion and laceration of cerebrum, unspecified, 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.
