Injury of femoral nrv at hip and thigh level, unsp leg, subs

This code signifies a documented injury to the femoral nerve within the hip or thigh region, occurring during a follow-up visit for a previously diagnosed condition. The specific leg affected is not identified in the medical record. This injury can result in motor weakness (e.g., difficulty extending the knee) and sensory deficits (e.g., numbness on the anterior thigh).

Use this code for subsequent encounters when a patient is receiving ongoing care for a femoral nerve injury at the hip or thigh level, and the medical documentation does not specify whether it's the left or right leg. This applies to situations such as follow-up appointments for physical therapy, medication management, or monitoring of recovery after an initial injury or surgical intervention.

• Ensure documentation clearly indicates a "subsequent encounter" for the injury.
• Only use this code when the laterality (left/right) of the affected leg is not specified in the medical record.
• Pair with an external cause code (V00-Y99) to describe the circumstances of the injury, if known and relevant to the encounter.
