Injury of tibial nerve at lower leg level, unsp leg, sequela

This code signifies a long-term or late-effect complication resulting from a past injury to the tibial nerve in the lower leg. The specific side (left or right) of the leg affected is not documented or is unknown. This could manifest as persistent pain, numbness, weakness, or other neurological deficits in the foot and ankle region.

Use this code when documenting a current condition that is a direct consequence of a previous injury to the tibial nerve in the lower leg, and the initial acute injury has resolved. This applies to situations where the patient is presenting for treatment of these residual symptoms, not the initial trauma. It is appropriate when laterality is not specified in the medical record.

• Always assign a "S" (sequela) seventh character for conditions representing late effects of an injury.
• Do not use this code for the initial acute injury; instead, use an acute injury code with the appropriate seventh character.
• Ensure documentation clearly links the current neurological deficit to a past tibial nerve injury in the lower leg.
