Pnctr w/o fb of r frnt wl of thorax w penet thor cav, init

This code signifies a penetrating injury to the right anterior chest wall, specifically a puncture wound that has breached the thoracic cavity. It indicates the absence of a retained foreign body and is for the initial treatment of the injury.

Apply this code for patients presenting with a stab wound, gunshot wound, or other sharp object injury to the right front chest that is confirmed to have entered the pleural space. This is appropriate for the initial encounter for treatment of such an injury, prior to definitive care or follow-up.

• Ensure documentation clearly specifies "right" side and "front wall" of the thorax.
• Confirm the wound is a "puncture" type and explicitly states "without foreign body."
• Verify the "initial encounter" status; subsequent care will require a different seventh character.
