What Deviated Nasal Septum ICD-10-CM codes can I use?

A deviated nasal septum occurs when the thin wall of cartilage and bone (the nasal septum) that divides the nasal cavity is off-center or crooked, making one nasal passage smaller. This condition can be congenital (present at birth) or acquired due to trauma, and it may contribute to nasal obstructions, sinus infections, snoring, and breathing difficulties.

It affects the nasal cavity, nasal turbinates, and nasal sinuses, and often requires medical or surgical intervention depending on the severity of symptoms. In ICD-10-CM, this condition is documented using specific diagnosis codes based on whether the deviation is congenital or acquired.

J34.2 – Deviated nasal septum

This ICD-10-CM code refers to an acquired deviated nasal septum, often resulting from trauma or injury to the nose.

Q67.4 – Other congenital deformities of skull, face, and jaw

This code is used when the deviated septum is present at birth and classified as a congenital deformity affecting the nasal structure.

Are these deviated nasal septum ICD codes billable?

Yes. Both of these ICD-10 codes for deviated nasal septum are valid and billable. It is essential to accurately use and document these codes, differentiating them from other unspecified disorders of the nose and nasal sinuses.

Clinical information

A deviated nasal septum refers to the displacement of the nasal septum, the bone and cartilage that divide the nasal cavity, which can further affect respiratory system functioning.

Symptoms may include:

  • Nasal obstruction
  • Chronic sinusitis
  • Nosebleeds
  • Facial pain
  • Headaches
  • Snoring or sleep apnea

Treatment options then include:

  • Medical: Decongestants, antihistamines, nasal corticosteroid sprays.
  • Surgical: Septoplasty to correct deviation

Synonyms include:

  • Acquired deviated nasal septum
  • Deviated nasal septum
  • Nasal deviation
  • Nasal deviation, bone
  • Nasal deviation, cartilage
  • Nasal septum deviation
  • Congenital deviated nasal septum
  • Deviated nasal septum due to injury
  • Deviated nasal septum due to trauma
  • Deviated nasal septum ICD 10
  • ICD 10 code for deviated nasal septum
  • ICD 10 deviated nasal septum

  • J34.2 deviated nasal septum

Frequently asked questions

How do healthcare professionals treat patients with deviated nasal septums?

Conservative treatment will include antihistamines and nasal decongestants. If the deviated nasal septum is severe, a surgical procedure known as septoplasty will be proposed. This procedure will straighten the nasal septum to improve airflow.

How long does it take for healthcare providers to accomplish deviated nasal septum surgery?

Septoplasty takes between 30 to 90 minutes for surgeons to accomplish.

What causes some people to be born with deviated nasal septums?

When the nose grows, the septum will sometimes lean to the side. This is common and normal. It’s only a cause for concern if the deviation is severe and is causing problems. Sometimes, it’s caused by connective tissue disease or by difficult births.
