Congenital pyriform aperture stenosis should be suspected in newborns with clinical signs of severe nasal obstruction associated with a difficulty to pass a small catheter though the anterior nasal valve. Timely recognition is mandatory to prevent a potential deadly outcome.
The ICD-10-CM code Q34.8 might also be used to specify conditions or terms like accessory structure of lower respiratory tract, congenital atresia of nasopharynx, congenital atresia of pharynx, congenital pulmonary alveolar capillary dysplasia, congenital respiratory biliary fistula, congenital stenosis of nasal pyriform aperture, etc.

The pyriform aperture is the most anterior and narrow opening of the bony nasal airways. It is limited laterally by the nasal process of the maxilla, inferiorly by the junction of the horizontal process of the maxilla and the anterior nasal spine, and superiorly by the nasal bones [2].
Pyriform aperture stenosis (PAS) is a very rare birth defect where the front opening of the nose is narrow due to an overgrowth in the upper jaw bone. PAS is sometimes associated with other abnormalities, including the presence of a single central incisor tooth and pituitary abnormalities.
noseThe anterior nasal aperture (piriform or pyriform aperture) is a heart- or pear-shaped opening it the skull. Its long axis is vertical, and narrow end upward; in the recent state it is much contracted by the lateral nasal cartilage and alar cartilages of the nose.
ICD-10 code J34. 89 for Other specified disorders of nose and nasal sinuses is a medical classification as listed by WHO under the range - Diseases of the respiratory system .
J38. 6 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM J38. 6 became effective on October 1, 2021.
Anatomical definition The nasal pyriform aperture is the bony anterior limitation of the nasal skeleton. The maxillary bone forms the inferior and lateral boarders and the nasal bone, forms the superior boarder, of this pear shaped aperture.
The pyriform sinus (also spelled piriform sinus and also known as the pyriform recess, pyriform fossa, and smuggler's fossa) is the pear-shaped subsite of the hypopharynx located posterolaterally to either side of the laryngeal opening.

ICD-10 code Q31. 1 for Congenital subglottic stenosis is a medical classification as listed by WHO under the range - Congenital malformations, deformations and chromosomal abnormalities .
Subglottic stenosis (SGS) is a narrowing of the airway below the vocal cords (subglottis) and above the trachea. Subglottic stenosis will involve narrowing of the cricoid, the only complete cartilage ring in the airway.
Laryngeal stenosis (LS) is a congenital or acquired narrowing of the larynx causing airway compromise. The acquired causes may be due to endotracheal intubation, trauma, burns, inflammation, neoplasms, autoimmune disorders and collagen vascular disease.
Q34.8 is a billable diagnosis code used to specify a medical diagnosis of other specified congenital malformations of respiratory system. The code Q34.8 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
Q34.8 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.
Pyriform aperture stenosis (PAS) is a very rare birth defect where the front opening of the nose is narrow due to an overgrowth in the upper jaw bone. PAS is sometimes associated with other abnormalities, including the presence of a single central incisor tooth and pituitary abnormalities.
Children with mild PAS will often be noisy but able to maintain their airway and feed appropriately. Children with severe PAS will often have significant distress, necessitating airway support and occasionally intubation. Symptoms include:
Newborns with PAS often have difficulty moving air through their nose shortly after birth. Since infants breathe only through their nose until they are about 4 months old, they are unable to compensate by breathing through their mouths. The degree of respiratory distress depends on the degree of nasal narrowing.
Treatment depends on the severity of the anomaly (unilateral or bilateral), how much it affects the child's breathing and eating as well as what other medical conditions the patient has.
