About ICD-9-CM 800.31
800.31 is an ICD-9-CM diagnosis code for closed fracture of vault of skull with other and unspecified intracranial 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 2 ICD-10-CM codes, such as S02.0XXA (Fracture of vault of skull, initial encounter for closed fracture) and S06.360A (Traumatic hemorrhage of cerebrum, unspecified, 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.
