Pnctr w fb of unsp front wall of thrx w penet thor cav, sqla

This code describes a long-term complication or late effect resulting from a puncture wound to the anterior chest wall, where a foreign object penetrated into the thoracic cavity. The specific location on the front chest wall is not documented.

Apply this code when documenting a sequela (e.g., chronic pain, adhesions, infection, or organ damage) that is a direct consequence of a past puncture injury to the front of the chest, involving a foreign body and penetration into the thoracic cavity. This code is used after the initial acute injury has healed.

• Assign this code only for conditions that are residual effects of a previously healed injury.
• Ensure documentation clearly links the current condition to the past penetrating chest wound with a foreign body.
• Do not use for acute injuries; refer to the acute injury codes for the initial encounter.
