Deviated Septum Explained
The nasal septum is a thin wall made of cartilage and bone that separates the left and right nasal passages. In a healthy nose, the septum sits in the center.
Common reasons for a deviated septum include: injury to your nose (trauma), or the natural growth of the nose.
A deviated septum will cause all of the following:
➤ Air flows out of only one nostril
➤ Air cannot come in equally through both nostrils
➤ Dryness/irritation in one/ or both nostrils
➤ Increased chance of developing sinusitis
In severe cases, it can significantly impact quality of life and may require surgical correction (septoplasty).
Common Symptoms of Deviated Septum
Patients with a deviated septum may experience:
- ➤Nasal congestion (often one-sided)
- ➤Difficulty breathing through the nose
- ➤Frequent nosebleeds
- ➤Snoring or sleep disturbances
- ➤Recurrent sinus infections
- ➤Facial pain or headaches
Causes of Deviated Septum
A deviated septum can develop due to:
1. Congenital Causes
- Present at birth due to abnormal development
2. Injury or Trauma
- Sports injuries
- Accidents
- Falls
3. Aging Factors
- Structural changes over time
Decision Guide – Which ICD-10 Code to Use?
Use this quick decision logic to choose the correct ICD-10 code:
- 👉 J34.2 → If septum is deviated (primary diagnosis)
- 👉 J32.9 → If patient has sinus infection
- 👉 J30.9 → If symptoms are allergy-related
- 👉 J34.3 → If turbinate enlargement is present
Pro Tip:
Always code the primary condition causing symptoms, not just the symptoms themselves.
Septum vs Other Nasal Conditions
