Sprain of calcaneofibular ligament of right ankle, sequela

This code signifies a chronic or late effect resulting from a previous sprain of the calcaneofibular ligament in the right ankle. It indicates persistent symptoms, complications, or conditions directly attributable to the initial injury, rather than an acute sprain.

Apply this code when documenting ongoing pain, instability, stiffness, or other long-term issues in the right ankle that are a direct consequence of a prior calcaneofibular ligament sprain. This is appropriate for follow-up visits addressing residual problems after the acute phase of the injury has passed.

• Always use this code as a secondary diagnosis, following a code that describes the specific sequela (e.g., chronic pain, instability).
• Ensure documentation clearly links the current condition to a previous calcaneofibular ligament sprain of the right ankle.
• Distinguish carefully from acute sprains, which would use codes from the initial encounter or subsequent encounter categories.
