Deviated nasal septum

This code signifies an acquired structural abnormality of the nasal septum, where the cartilaginous or bony wall dividing the nasal passages is displaced from the midline. This deviation can obstruct airflow, leading to symptoms such as difficulty breathing, recurrent epistaxis, or chronic sinusitis. It is not present at birth but develops later in life.

Apply this code when documentation indicates an acquired deviation of the nasal septum, often noted during an ENT examination. Supporting documentation should describe the presence of a deviated septum and may include details about associated symptoms like nasal obstruction or impaired breathing. This code is appropriate for patients presenting with symptoms attributable to the septal deviation.

• Do not use this code if the documentation specifies a congenital deviated nasal septum; refer to Q67.4 instead.
• Ensure the medical record clearly distinguishes between acquired and congenital forms of septal deviation.
• Consider coding associated conditions, such as chronic sinusitis (J32.-) or nasal polyps (J33.-), if documented and clinically supported.
