Nondisplaced Maisonneuve's fracture of left leg, sequela

This code signifies a healed or resolving Maisonneuve's fracture of the left leg that was nondisplaced at the time of injury. A Maisonneuve's fracture involves a spiral fracture of the proximal fibula with an associated injury to the deltoid ligament and/or medial malleolus, and disruption of the tibiofibular syndesmosis. The "sequela" designation indicates that the patient is still receiving care for the residual effects or complications of the original injury.

Use this code for follow-up encounters when a patient is being treated for ongoing issues related to a previously sustained, nondisplaced Maisonneuve's fracture of the left leg. This includes scenarios such as physical therapy for rehabilitation, management of chronic pain, or assessment of long-term instability or arthritis resulting from the fracture. It is appropriate when the acute phase of healing has passed, but the patient's care is still directly linked to the fracture.

• Always assign an additional code for any specific sequela or complication being treated (e.g., M25.542 for chronic left ankle pain).
• Ensure documentation clearly specifies "nondisplaced" and "left leg" to support this code.
• Do not use this code for the initial acute injury; use the appropriate acute fracture code (e.g., S82.862A) for the initial encounter.
