813.11 — Open fracture of olecranon process of ulna
About ICD-9-CM 813.11
813.11 is an ICD-9-CM diagnosis code for open fracture of olecranon process of 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 4 ICD-10-CM codes, such as S52.023B (Displaced fracture of olecranon process without intraarticular extension of unspecified ulna, initial encounter for open fracture type I or II), S52.023C (Displaced fracture of olecranon process without intraarticular extension of unspecified ulna, initial encounter for open fracture type IIIA, IIIB, or IIIC) and S52.026B (Nondisplaced fracture of olecranon process without intraarticular extension of unspecified ulna, initial encounter for open fracture type I or II). All of these are approximate matches, so review the record to pick the right one.
