About ICD-9-CM 821.31
821.31 is an ICD-9-CM diagnosis code for open fracture of condyle, femoral. 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 S72.413B (Displaced unspecified condyle fracture of lower end of unspecified femur, initial encounter for open fracture type I or II), S72.413C (Displaced unspecified condyle fracture of lower end of unspecified femur, initial encounter for open fracture type IIIA, IIIB, or IIIC) and S72.416B (Nondisplaced unspecified condyle fracture 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.
