Injury of unsp nerve at hip and thi lev, unsp leg, sequela

This code signifies a long-term or late effect resulting from an injury to an unspecified nerve located in the hip or thigh region of an unspecified leg. The original acute injury has resolved, but the patient continues to experience symptoms or complications directly attributable to that past nerve damage.

Apply this code when documentation clearly indicates a sequela (e.g., chronic pain, weakness, sensory deficits) stemming from a previous, unspecified nerve injury in the hip or thigh. This is appropriate when the specific nerve involved is not identified, and the laterality of the leg is also not specified. It is used after the acute phase of the original injury has passed.

• Always sequence this sequela code after the code for the specific sequela (e.g., chronic pain, muscle weakness).
• Avoid using this code if the specific nerve (e.g., femoral, sciatic) or the affected leg (right/left) is documented; instead, use a more specific sequela code.
• Ensure the "S" seventh character is used to indicate sequela, confirming the injury's long-term effect.
