Injury of acoustic nerve, right side, sequela

This code signifies a long-term or late effect resulting from a previous injury to the acoustic nerve on the right side. This could manifest as persistent hearing loss, tinnitus, or balance issues directly attributable to the past trauma.

Apply this code when documentation clearly indicates a current condition stemming from a prior injury to the right acoustic nerve, and the acute phase of the original injury has passed. This is appropriate for chronic or residual symptoms. The patient's medical record should specify the right side and the sequela nature of the current presentation.

• Always sequence the sequela code first, followed by codes for the specific residual condition(s) (e.g., hearing loss, tinnitus).
• Ensure documentation specifies "sequela" or "late effect" and clearly links the current symptoms to a past right acoustic nerve injury.
• Do not use this code for acute injuries; instead, refer to the acute injury codes within the S04 category.
