2025 ICD-10-CM code Q30.0
Choanal atresia. This is a congenital blockage of the nasal passages, usually by bone or membrane.
Medical necessity is established by the presence of respiratory distress, feeding difficulties, or chronic nasal obstruction caused by the congenital blockage. Treatment is necessary to restore normal breathing and prevent complications.
Diagnosis and management of this condition are typically handled by otolaryngologists (ENT specialists) and pediatricians. They are responsible for confirming the diagnosis, determining the severity, and recommending appropriate treatment.
In simple words: Choanal atresia is a birth defect where the back of the nasal passage is blocked, making it difficult for a baby to breathe through their nose.
Congenital blockage of the posterior nasal aperture, which may be bony or membranous, on one or both sides. The blockage prevents newborns from breathing adequately through their nose.
Example 1: A newborn infant has difficulty breathing and turns blue when feeding. Examination reveals a blockage at the back of the nasal passages., A two-week-old baby has persistent nasal congestion and noisy breathing. Imaging studies confirm the presence of choanal atresia., An older child presents with chronic nasal obstruction and recurrent sinus infections. A CT scan shows bony atresia of the choanae.
Diagnosis requires physical examination findings and imaging studies such as CT scan or nasal endoscopy. Document the type of atresia (unilateral or bilateral, bony or membranous) and any associated symptoms or malformations.
