About ICD-9-CM 821.21

821.21 is an ICD-9-CM diagnosis code for closed 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 2 ICD-10-CM codes, such as S72.413A (Displaced unspecified condyle fracture of lower end of unspecified femur, initial encounter for closed fracture) and S72.416A (Nondisplaced unspecified condyle fracture of lower end of unspecified femur, initial encounter for closed fracture). All of these are approximate matches, so review the record to pick the right one.
