Inj oth blood vessels of thorax, unsp side, sequela

This code signifies a long-term or late effect resulting from a past injury to a blood vessel within the thoracic cavity, excluding the heart and great vessels, where the specific type of blood vessel is not further identified. It indicates a residual condition or complication that arose after the initial healing of the original trauma.

Use this code when documenting a chronic issue, such as a persistent aneurysm, stricture, or other functional impairment, that is directly attributable to a previous, unspecified injury of a thoracic blood vessel. This applies when the original injury has healed, but its lasting consequences are still present and require ongoing management.

• Always sequence this sequela code after the code for the specific residual condition it describes.
• Ensure documentation clearly links the current condition to a past injury of a thoracic blood vessel.
• Avoid using this code for acute injuries; it is strictly for sequelae.
