External constriction of right front wall of thorax, sequela

This code signifies a long-term or residual effect resulting from an external constriction injury to the right anterior chest wall. This could manifest as chronic pain, scarring, nerve damage, or functional limitations that persist after the initial injury has healed. It indicates that the constriction event is in the patient's past, but its consequences are still present.

Apply this code when documenting a patient presenting with ongoing symptoms or conditions directly attributable to a previous external constriction injury of the right front thorax. This is appropriate for follow-up visits where the sequelae are being managed, or when evaluating a new patient whose current issues stem from such a past event.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, scar, nerve entrapment).
• Ensure documentation clearly links the current condition to the past external constriction injury of the right front thorax.
• The "S" seventh character indicates sequela, meaning the initial injury has healed, but its lasting effects are being treated.
