957.9
ICD-9-CMThis code signifies an injury affecting a nerve or nerves, where the specific anatomical location of the damage is not documented. It encompasses a broad range of nerve traumas, such as contusions, lacerations, or compressions, without specifying the affected peripheral or cranial nerve.
This code is appropriate when a patient presents with symptoms of nerve injury (e.g., pain, numbness, weakness, paralysis) following trauma, but the physician documentation does not identify the precise nerve involved. It is used when the diagnostic workup is incomplete or when the injury is diffuse and not localized to a single nerve.
