About ICD-9-CM 824.5
824.5 is an ICD-9-CM diagnosis code for bimalleolar fracture, open. 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 S82.843B (Displaced bimalleolar fracture of unspecified lower leg, initial encounter for open fracture type I or II), S82.843C (Displaced bimalleolar fracture of unspecified lower leg, initial encounter for open fracture type IIIA, IIIB, or IIIC) and S82.846B (Nondisplaced bimalleolar fracture of unspecified lower leg, initial encounter for open fracture type I or II). All of these are approximate matches, so review the record to pick the right one.
