Congenital malformations of nose (Q30)
The ICD-10 codes in the Q30 category classify various congenital malformations of the nose. These codes help specifically identify developmental nasal abnormalities present at birth, such as choanal atresia (Q30.0) and agenesis or underdevelopment of the nose (Q30.1), among others.
These diagnosis codes cover a range of nasal deformities, from complete or partial blockage of the nasal passage like choanal atresia; also known by terms such as posterior or anterior nares atresia; to structural variations such as a bifid or cleft nose (Q30.2), and rare anomalies like congenital perforated nasal septum (Q30.3). The section also includes less common or unspecified nose malformations (Q30.8, Q30.9), which incorporate conditions sometimes described as supratip dysplasia, saddle nose, or even whole nasal agenesis. Recognizing these synonyms alongside their corresponding ICD-10 codes aids healthcare professionals and coders in accurately documenting conditions related to congenital nasal malformations. This precise classification supports appropriate diagnosis, treatment planning, and health records management.

Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Choanal Atresia
A congenital abnormality that is characterized by a blocked CHOANAE, the opening between the nose and the NASOPHARYNX. Blockage can be unilateral or bilateral; bony or membranous.
