About ICD-9-CM 801.50

801.50 is an ICD-9-CM diagnosis code for open fracture of base of skull without mention of intracranial injury, unspecified state 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 S02.101B (Fracture of base of skull, right side, initial encounter for open fracture), S02.102B (Fracture of base of skull, left side, initial encounter for open fracture) and S02.109B (Fracture of base of skull, unspecified side, initial encounter for open fracture). All of these are approximate matches, so review the record to pick the right one.
