ICD-10-CMNondisplaced bimalleolar fracture of unspecified lower leg, initial encounter for open fracture type IIIA, IIIB, or IIIC
This code describes a fracture involving both the medial and lateral malleoli of the ankle, where the bone fragments remain in their normal anatomical alignment. The fracture is open, meaning the skin and soft tissues have been compromised, and is classified as a severe open fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC) due to significant soft tissue damage, contamination, or extensive periosteal stripping. This is for the initial treatment of the injury.
Use this code for a patient presenting with a newly diagnosed bimalleolar ankle fracture that is documented as nondisplaced and involves an open wound communicating with the fracture site, specifically categorized as Gustilo-Anderson type IIIA, IIIB, or IIIC. This code is appropriate for the initial encounter where definitive treatment for the fracture is being provided.
