Nondisplaced Maisonneuve's fracture of unsp leg, sequela

This code signifies a healed or residual condition resulting from a Maisonneuve's fracture of an unspecified leg, where the fracture fragments were not displaced at the time of injury. A Maisonneuve's fracture is a specific type of ankle injury involving a spiral fracture of the proximal fibula with an associated injury to the medial ankle structures and/or deltoid ligament, and disruption of the tibiofibular syndesmosis. The "sequela" indicates that this code is used for late effects or complications of the original injury, rather than the acute phase.

Use this code when documenting a patient presenting for follow-up care, evaluation of long-term complications (e.g., chronic pain, instability, arthritis), or management of residual issues directly attributable to a previously sustained, nondisplaced Maisonneuve's fracture of an unspecified leg. This code is appropriate when the acute phase of treatment for the fracture has concluded.

• Always assign a sequela code (S00-T88 with a 7th character of 'S') for conditions that are residual effects of a previous injury.
• Ensure documentation clearly links the current condition to the prior Maisonneuve's fracture.
• If the laterality (left or right leg) is known, a more specific code should be used.
