External constriction of middle front wall of thorax, subs

This code signifies an external compression or binding affecting the central anterior chest wall, occurring during a follow-up visit. This constriction could be due to various external factors, such as tight clothing, bandages, or other objects, leading to pressure on the sternum and surrounding structures.

Use this code for patients presenting for subsequent care related to a previously diagnosed external constriction of the middle front wall of the thorax. This includes follow-up appointments for monitoring healing, assessing complications, or adjusting treatment after the initial injury or event.

• Ensure the documentation clearly indicates a "subsequent encounter" for this specific injury.
• Distinguish from initial encounters (initial episode of care) or sequela (late effects).
• Always code the underlying cause of the external constriction if known and documented.
