Injury to other specified cranial nerves

This code signifies damage or dysfunction affecting any cranial nerve not specifically categorized elsewhere, such as the olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharyngeal, vagus, or hypoglossal nerves. It represents a broad category for cranial nerve injuries that are specified but lack a more precise ICD-9-CM code.

Use this code when documentation clearly indicates an injury to a cranial nerve that does not have a dedicated, more specific ICD-9-CM code. This often applies to less common or ambiguously described cranial nerve injuries where the specific nerve is identified but falls outside the more common categories. Supporting documentation should specify the cranial nerve involved and the nature of the injury.

• Ensure the documentation explicitly states "injury" to a cranial nerve, not just a disorder or disease.
• Always review for more specific ICD-9-CM codes for individual cranial nerve injuries before resorting to this code.
• This code requires a secondary code to identify the cause of the injury (e.g., E-code for external cause).
