ICD-10-CMNondisplaced Maisonneuve's fracture of right leg, initial encounter for open fracture type I or II
This code signifies a fracture of the right fibula, specifically a Maisonneuve's fracture, which is characterized by a spiral fracture of the proximal fibula with an associated ankle injury. In this case, the bone fragments are still in their normal anatomical alignment (nondisplaced), and the fracture has broken through the skin, but the wound is relatively clean and small (Type I or II open fracture).
Use this code for initial encounters with patients presenting with a newly diagnosed, nondisplaced Maisonneuve's fracture of the right leg where the fracture has created an open wound classified as Type I or II. This applies to the acute phase of injury and treatment.
