ICD-10-CM Code For Congenital Malformations Of Nose: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group Q30 includes congenital anomalies of the nose such as absent or underdeveloped nasal structures, choanal atresia, and other developmental nasal deformities that affect form and function. These ICD-10-CM diagnosis codes are used to document congenital nasal malformations in newborns and children, capturing anatomic involvement, laterality, and clinical complexity relevant to airway obstruction and reconstructive needs. Accurate coding within the ICD-10-CM Q30 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM Q30: Congenital Malformations Of Nose Overview

The ICD-10-CM Q30 group covers congenital malformations of the nose, including developmental anomalies of external nasal structures and internal nasal passages that are present at birth. These conditions affect the respiratory system and can impact breathing, airway patency, and facial development. Accurate coding supports clinical communication and is important for appropriate reimbursement and care planning.

When to Use

Use codes from this group when a congenital nasal malformation is diagnosed and documented by the provider, including in newborns, infants, or later in life when congenital findings are identified. Apply the most specific code that reflects the anatomical site and laterality, and include additional codes for associated conditions or complications as documented.

ICD-10-CM Code	Description
Q30.0	Choanal atresia
Q30.1	Agenesis and underdevelopment of nose
Q30.2	Fissured, notched and cleft nose
Q30.3	Congenital perforated nasal septum
Q30.8	Other congenital malformations of nose
Q30.9	Congenital malformation of nose, unspecified

DRG Codes

DRG Code	Description
154	Other Ear, Nose, Mouth and Throat Diagnoses with MCC
155	Other Ear, Nose, Mouth and Throat Diagnoses with CC
156	Other Ear, Nose, Mouth and Throat Diagnoses without CC/MCC

Typical Clinical Scenarios

A newborn delivered at term is noted on initial neonatal exam to have an absent external nasal passage on one side with respiratory distress and difficulty feeding; otolaryngology and neonatology evaluate for airway compromise and plan imaging and possible surgical airway reconstruction. A congenital structural anomaly of the nose causing obstruction is documented and coded. Typical codes: Q30.0, Q30.9
A school-age child with lifelong cosmetic concerns and nasal breathing difficulty is evaluated in clinic for a visibly bifid or duplicated external nose and chronic nasal obstruction interfering with exercise and sinus drainage; surgical consultation is obtained for septorhinoplasty and functional correction. The encounter documents a congenital malformation of the external nose as the primary diagnosis. Typical codes: Q30.1, Q30.8
An adult presents to the emergency department after a motor vehicle collision in which preexisting congenital narrowing of the nasal cavity complicated the airway management and contributed to epistaxis and difficult intubation; records note a congenital intrinsic nasal stenosis discovered during airway assessment, which affects acute care planning and coding. Typical codes: Q30.2, Q30.9
