Laceration of lung, unilateral, initial encounter

This code signifies a tear or cut in one lung, typically resulting from trauma. This injury can compromise respiratory function and may lead to complications such as pneumothorax or hemothorax. It indicates the initial phase of treatment for this specific lung injury.

Use this code for patients presenting with a newly diagnosed laceration affecting only one lung, often due to blunt or penetrating chest trauma. This applies when the patient is receiving active treatment for the injury, such as surgical repair, chest tube insertion, or initial stabilization.

• Ensure documentation clearly specifies "unilateral" to differentiate from bilateral lung involvement.
• Confirm the encounter is the "initial encounter" for this specific injury, meaning the patient is receiving active treatment.
• Look for associated external cause codes (e.g., W-codes, Y-codes) to fully describe the circumstances of the injury.
