About ICD-9-CM 813.53
813.53 is an ICD-9-CM diagnosis code for open fracture of distal 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 S52.609B (Unspecified fracture of lower end of unspecified ulna, initial encounter for open fracture type I or II) and S52.609C (Unspecified fracture of lower end of unspecified ulna, initial encounter for open fracture type IIIA, IIIB, or IIIC). All of these are approximate matches, so review the record to pick the right one.
