Nondisplaced Maisonneuve's fracture of right leg, sequela

This code describes a healed or residual condition resulting from a Maisonneuve's fracture of the right leg, where the fracture fragments were not displaced 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" indicates that the acute injury has passed, and the patient is now presenting with long-term effects or complications.

Use this code when documenting follow-up care for a patient who previously sustained a nondisplaced Maisonneuve's fracture of the right leg and is now experiencing persistent symptoms, complications, or long-term effects related to that past injury. This could include chronic pain, instability, limited range of motion, or post-traumatic arthritis in the ankle or lower leg due to the prior fracture.

• Always assign a "sequela" code when the patient is seen for a complication or late effect of a past injury, not for the initial acute treatment.
• Ensure documentation clearly states the fracture was nondisplaced and specifies the right leg.
• Consider additional codes for specific sequelae, such as chronic pain (G89.29) or post-traumatic arthritis (M19.171), if applicable and supported by the medical record.
