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

This code signifies damage to the femoral nerve in the left hip and thigh region that is being addressed in a follow-up encounter. This injury can result in sensory deficits, motor weakness, or paralysis in the anterior thigh and medial leg, impacting knee extension and hip flexion.

Apply this code for patients presenting for ongoing treatment, rehabilitation, or follow-up care related to a previously diagnosed injury of the left femoral nerve at the hip or thigh level. This includes scenarios such as physical therapy sessions, re-evaluation of nerve function, or management of persistent symptoms after initial treatment.

• Ensure the documentation clearly specifies the left leg and the hip/thigh level of the femoral nerve injury.
• Verify that the encounter is indeed a "subsequent encounter" for the injury, not an initial treatment or sequela.
• Pair this code with external cause codes (V, W, X, Y categories) to describe the circumstances of the injury, if applicable and known.
