Injury to other specified nerve(s)

This code signifies traumatic damage to a peripheral nerve not otherwise classified, such as the radial, ulnar, median, or sciatic nerve. It encompasses various types of injury, including contusions, lacerations, compressions, or avulsions affecting the function of these specific nerves. The injury results in neurological deficits corresponding to the affected nerve's distribution.

Use this code when documentation clearly indicates an injury to a named peripheral nerve (e.g., "laceration of the ulnar nerve," "compression neuropathy of the radial nerve due to fracture") that isn't covered by more specific codes for cranial or spinal nerves. Supporting documentation should detail the mechanism of injury, the specific nerve involved, and the resulting neurological impairment.

• Ensure the documentation specifies a named peripheral nerve; avoid using for general nerve pain or unspecified neuropathy.
• Always code the underlying cause of the injury (e.g., fracture, open wound) first, followed by this code for the nerve injury.
• Distinguish from codes for nerve root injuries (spinal nerves) or cranial nerve injuries, which have their own specific classifications.
