Unsp injury of blood vessels of thorax, right side, sequela

This code indicates a long-term or late effect of an unspecified injury to a blood vessel, other than the major arteries or veins, located on the right side of the chest. This could include damage to smaller arteries, veins, or capillaries within the thoracic cavity, where the specific type of vessel or injury is not documented.

Use this code when documenting a sequela (a condition that is the result of a previous disease or injury) of an unspecified right-sided thoracic blood vessel injury. This is appropriate when the original injury occurred in the past and the patient is now presenting with a residual effect, and the specific vessel or nature of the initial injury is not detailed.

• Requires a seventh character "S" to indicate sequela, meaning the patient is being treated for a complication or residual effect of the original injury.
• Always sequence this sequela code after the code(s) for the specific residual condition(s) being treated.
• Avoid using this code if a more specific code for the injured blood vessel (e.g., specific artery or vein) or type of injury is available.
