External constrict of bi front wall of thorax, sequela

This code signifies a long-term or late-effect condition resulting from external pressure or compression on both sides of the anterior chest wall. This constriction can impact respiratory function or cause other persistent symptoms due to the previous external force. It indicates that the initial injury or cause of the constriction is no longer acute, but its effects remain.

Apply this code when documenting a patient presenting with ongoing symptoms or complications directly attributable to a past external constriction of the bilateral front wall of the thorax. This includes cases where a previous injury, tight binding, or other external force caused the initial constriction, and the patient is now being treated for its residual effects. It is appropriate for follow-up encounters addressing these chronic issues.

• Always use this code as a secondary diagnosis, following the code for the primary condition or sequela being treated.
• Ensure documentation clearly links the current symptoms or condition to a past external constriction of the bilateral front wall of the thorax.
• Verify the "S" seventh character is appropriate, indicating a sequela or late effect, not an acute injury.
