Pnctr w fb of l frnt wl of thorax w penet thor cavity, init

This code describes a penetrating injury to the left anterior chest wall caused by a sharp object, where a foreign body remains embedded and has breached the pleural space or mediastinum. This type of wound carries a high risk of damage to underlying thoracic organs.

Apply this code for patients presenting with a left-sided puncture wound to the front of the chest, where imaging or surgical exploration confirms the presence of a foreign body that has entered the thoracic cavity. This is used for the initial treatment of such an injury.

• Ensure documentation clearly specifies "left front wall" and "with penetration into thoracic cavity."
• Confirm the presence of a foreign body is explicitly stated in the medical record.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
