Acquired absence of lung [part of]

📋Clinical Description

This code indicates the complete or partial absence of a lung that was acquired after birth, typically due to surgical removal (pneumonectomy or lobectomy) or severe disease processes. It signifies a permanent anatomical alteration affecting respiratory function.

🎯When to Use

Use this code for patients who have undergone surgical removal of a lung or a significant portion of a lung due to conditions like lung cancer, severe emphysema, or extensive infection. It is also applicable for non-surgical acquired absence, such as from severe trauma or congenital anomalies that manifest later in life.

💡Coding Tips

Always specify the underlying reason for the acquired absence, if known, with an additional code.
Distinguish between congenital absence (Q33.3) and acquired absence.
This code is for the absence of the lung, not the condition that led to its removal.
