Unspecified injury of neck, sequela

This code signifies a long-term complication or late effect stemming from an unspecific injury to the neck. It indicates that the original acute injury has resolved, but residual symptoms or conditions persist as a direct result of that past trauma. The specific nature of the original neck injury is not documented or is unknown.

This code is appropriate when a patient presents with a current condition that is a sequela of a previously sustained, but unspecified, neck injury. Documentation should clearly link the current symptom or condition to a past neck injury, even if the exact nature of the original injury (e.g., sprain, fracture) is not specified. This code is used after the acute phase of the initial injury has passed.

• Always sequence the sequela code (S19.9XXS) after the code describing the specific residual condition or symptom.
• Avoid using this code if the specific nature of the original neck injury is known and documented; instead, use the appropriate sequela code for that specific injury type.
• Ensure documentation explicitly states the current condition is a "sequela," "late effect," or "due to old injury" of the neck.
