Lac w/o fb of unsp front wall of thrx w penet thor cav, init

This code signifies a tear or cut on the front chest wall that extends through the muscle and tissue layers, breaching the thoracic cavity, but without any foreign object embedded in the wound. The exact location on the front chest wall is not specified.

Use this code for initial encounters with patients presenting with a penetrating laceration to the anterior chest, such as from a stab wound or a deep cut, where the injury has clearly entered the chest cavity. This applies when no foreign body is found within the wound and the specific side (left or right) of the anterior chest is not documented.

• Ensure documentation explicitly states "penetration into thoracic cavity" and "without foreign body."
• If the specific location (e.g., left or right front wall) is documented, a more specific code should be used.
• This code is for the initial encounter; subsequent encounters would require a different 7th character.
