Injury of abducent nerve, right side, sequela

This code signifies a long-term neurological deficit affecting the right abducent nerve (cranial nerve VI), responsible for lateral eye movement. This injury results in persistent symptoms such as diplopia (double vision) or strabismus (eye misalignment) due to impaired abduction of the right eye.

Apply this code when documenting a chronic or residual condition stemming from a previous injury to the right abducent nerve. Documentation should clearly indicate a past injury as the etiology and the current presentation as a lasting consequence, such as persistent right lateral rectus palsy.

• Requires a seventh character 'S' for sequela, indicating a late effect of an earlier injury.
• Do not use for acute abducent nerve injuries; refer to acute injury codes (e.g., S04.41XA).
• Code also any associated conditions or symptoms, such as diplopia (H53.2) or strabismus (H50.x), if present.
