About ICD-9-CM 813.04

813.04 is an ICD-9-CM diagnosis code for other and unspecified closed fractures of proximal end of ulna (alone). 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 S52.009A (Unspecified fracture of upper end of unspecified ulna, initial encounter for closed fracture) and S52.099A (Other fracture of upper end of unspecified ulna, initial encounter for closed fracture). All of these are approximate matches, so review the record to pick the right one.
