Injury of lateral plantar nerve, right leg, sequela

This code signifies a long-term or residual effect resulting from a past injury to the lateral plantar nerve in the right foot. This nerve, a branch of the tibial nerve, supplies sensation to the sole of the foot and innervates several intrinsic foot muscles. Sequelae can include chronic pain, numbness, weakness, or altered sensation in the affected area.

Apply this code when documenting a current condition that is a direct consequence of a previous injury to the right lateral plantar nerve, and the acute phase of the original injury has passed. This is appropriate for follow-up encounters where the patient is being treated for persistent symptoms related to the old injury.

• Ensure documentation clearly links the current condition to a past injury of the right lateral plantar nerve.
• Always use this "S" code with a seventh character of "S" for sequela, indicating a late effect.
• Code any current, specific manifestations of the sequela (e.g., chronic pain, muscle weakness) in addition to this code.
