Injury of other cranial nerves, right side, sequela

This code signifies a long-term or late effect resulting from a past injury to any cranial nerve on the right side, excluding the optic and acoustic nerves. It indicates that the patient is experiencing residual symptoms or complications directly attributable to a previous trauma affecting these specific nerves.

Use this code when documentation clearly indicates a current condition or symptom that is a direct consequence of an old injury to a right-sided cranial nerve (other than optic or acoustic). This applies when the acute phase of the original injury has passed, and the patient presents with chronic neurological deficits such as persistent facial paralysis, trigeminal neuralgia, or glossopharyngeal nerve dysfunction due to the prior trauma.

• Always sequence the code for the specific sequela (e.g., facial paralysis) first, followed by this S-code to indicate the cause.
• Ensure documentation specifies "right side" and clearly links the current condition to a past injury of a cranial nerve other than the optic (II) or acoustic (VIII).
• Do not use for acute injuries; this code is exclusively for sequelae.
