Injury of facial nerve, right side, sequela

This code signifies a long-term consequence or late effect resulting from a past injury to the facial nerve on the right side. It indicates that the initial injury has resolved, but the patient continues to experience residual symptoms or deficits directly attributable to that prior trauma.

Apply this code when documentation clearly indicates a current condition or symptom (e.g., facial paralysis, synkinesis, or contracture) that is a direct sequela of a previously sustained injury to the right facial nerve. The patient's medical history should confirm the prior injury and its resolution.

• Requires a seventh character "S" to denote sequela, indicating a complication or condition arising as a direct result of a previous injury.
• Always sequence this sequela code after the code(s) for the specific residual condition(s) being treated (e.g., G51.0 for facial nerve palsy).
• Ensure documentation explicitly links the current symptoms to a past right facial nerve injury, not an acute or ongoing injury.
