Injury of nerves at ankle and foot level, unsp leg, sequela

This code signifies a long-term or late-effect complication resulting from a previous injury to any nerve in the ankle or foot region, excluding those specifically categorized elsewhere. It indicates that the specific nerve affected is not precisely documented, and the laterality (left or right leg) is also unspecified.

Apply this code when a patient presents with a chronic or residual condition directly attributable to an old, resolved injury of an unspecified nerve in the ankle or foot. This is appropriate when the original injury has healed, but its lasting effects, such as persistent pain, numbness, weakness, or altered sensation, are being treated.

• Always assign an external cause code (V00-Y99) to describe the original injury that led to the sequela.
• Use this code only when the specific nerve involved and the affected leg are not documented. If known, use a more specific code.
• This code should be a secondary diagnosis, with the primary diagnosis reflecting the current manifestation of the sequela (e.g., chronic pain, neuropathy).
