In simple words: The baby was born with a hole in the cartilage or bone wall between their nostrils.

This code signifies a congenital (present at birth) perforation (hole) in the nasal septum, the cartilage and bone dividing the nostrils.This condition can vary in size and location within the septum and may be associated with other congenital anomalies.

Example 1: A newborn infant presents with respiratory distress. Examination reveals a visible perforation in the nasal septum, causing difficulty breathing. The code Q30.3 is used., During a routine physical exam, a child is found to have a small, asymptomatic perforation in the nasal septum.The history is consistent with this being a congenital condition. Code Q30.3 is applied., A teenager with a history of nasal obstruction and recurrent infections is diagnosed with a large septal perforation.Imaging confirms a congenital etiology. Q30.3 is used to document this finding.

Detailed clinical examination findings, including location and size of the perforation.Prenatal history, if available, to rule out acquired causes. Imaging studies (e.g., nasal endoscopy) if performed.

** The severity of the perforation may influence clinical management. Small, asymptomatic perforations may not require intervention, while larger perforations could impact breathing and necessitate surgical repair.
