821.33 — Open supracondylar fracture of femur
About ICD-9-CM 821.33
821.33 is an ICD-9-CM diagnosis code for open supracondylar fracture of femur. 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 S72.453B (Displaced supracondylar fracture without intracondylar extension of lower end of unspecified femur, initial encounter for open fracture type I or II), S72.453C (Displaced supracondylar fracture without intracondylar extension of lower end of unspecified femur, initial encounter for open fracture type IIIA, IIIB, or IIIC) and S72.456B (Nondisplaced supracondylar fracture without intracondylar extension of lower end of unspecified femur, initial encounter for open fracture type I or II). All of these are approximate matches, so review the record to pick the right one.
