Contusion of thorax, unspecified, sequela

This code signifies a bruise or blunt injury to the chest wall, where the specific location within the thorax is not documented. It is used to indicate a long-term effect or complication arising from such an initial injury.

Apply this code when a patient presents with a current condition that is a direct consequence of a past, unspecified contusion to the thorax. This is appropriate for follow-up encounters addressing residual pain, scarring, or other chronic issues stemming from the original injury.

• Requires a seventh character of 'S' for sequela, indicating a late effect.
• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a previous thoracic contusion.
