Injury of unspecified nerves of neck, sequela

This code signifies a long-term complication or late effect resulting from an injury to an unspecified nerve in the neck region. It indicates that the initial acute injury has resolved, but residual symptoms or conditions persist due to the nerve damage.

Apply this code when documentation clearly states a sequela (e.g., chronic pain, weakness, numbness, or paralysis) directly attributable to a past, unspecified nerve injury of the neck. This code is appropriate when the specific nerve involved in the original injury is not identified.

• Always use a seventh character "S" for sequela, indicating a late effect.
• Code the specific nature of the sequela (e.g., chronic pain, muscle weakness) first, followed by this code.
• Ensure documentation explicitly links the current condition to a past neck nerve injury and specifies the nerve as "unspecified."
