Injury of deep peroneal nrv at ank/ft level, left leg, init

This code signifies damage to the deep peroneal nerve in the left ankle or foot region. This nerve is crucial for dorsiflexion of the foot and sensation to the web space between the first and second toes. Injury can result in weakness, numbness, or a "foot drop" gait.

Apply this code when documenting an acute injury to the deep peroneal nerve affecting the left lower extremity at the ankle or foot. This is appropriate for initial evaluations of new trauma, such as a fracture, sprain, or direct impact causing nerve damage.

• Ensure laterality (left leg) is accurately documented and selected.
• Verify the encounter type is "initial" for the first treatment of the injury.
• Distinguish from superficial peroneal nerve injuries, which have different code assignments.
