Sprain of tibiofibular ligament of unsp ankle, sequela

This code signifies a long-term or late effect resulting from a sprain of the tibiofibular ligament in an ankle where the specific side (left or right) is not documented. It indicates that the initial injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to that past sprain.

Apply this code when documenting follow-up care for chronic pain, instability, stiffness, or other persistent issues in an unspecified ankle, clearly linked to a previous tibiofibular ligament sprain. This is appropriate when the acute phase of the injury has passed, and the current encounter addresses the lasting consequences.

• Ensure the medical record explicitly states the sequela is due to a previous tibiofibular ligament sprain.
• Only use this code when the laterality of the affected ankle is not specified in the documentation.
• Always code the specific sequela (e.g., chronic pain, instability) first, followed by this code as a secondary diagnosis.
