About ICD-9-CM 813.23

813.23 is an ICD-9-CM diagnosis code for closed fracture of shaft of radius with ulna. 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 S52.209A (Unspecified fracture of shaft of unspecified ulna, initial encounter for closed fracture) and S52.309A (Unspecified fracture of shaft of unspecified radius, initial encounter for closed fracture). 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.
