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

This code signifies an injury to the deep peroneal nerve, located at the ankle or foot, where the specific leg affected is not documented. This nerve is crucial for dorsiflexion of the foot and sensation to the first web space, so injury can result in foot drop or sensory deficits. The "initial encounter" designation indicates the patient is receiving active treatment for this specific injury.

Apply this code when documentation clearly states a deep peroneal nerve injury at the ankle or foot, but the medical record does not specify whether it's the right or left leg. This is appropriate for initial evaluations, surgical repairs, or other active treatments for the acute injury. It should be used when the cause of the injury (e.g., trauma, compression) is not yet determined or is not the primary focus of the encounter.

• Only use this code when the laterality (right/left) is truly unspecified in the medical record.
• Ensure the encounter is for active treatment of the injury, not follow-up care or sequelae.
• Look for documentation of foot drop, numbness in the first web space, or direct trauma to the anterior ankle/foot.
