ICD10 code of Laryngomalacia and ICD9 code

The ICD-10 code for laryngomalacia is Q31.5, while the corresponding ICD-9 code is 748.2. These codes are used by healthcare providers to classify this common congenital laryngeal anomaly, which is characterized by the inward collapse of supraglottic tissues during inhalation.

What is the clinical nature of laryngomalacia?

Laryngomalacia is the most common cause of persistent inspiratory stridor in infants. It occurs due to the immaturity of the laryngeal cartilage, which is excessively floppy and causes partial airway obstruction when the infant breathes in. While many cases are mild and resolve on their own by 18 to 24 months, it is vital to monitor for signs of distress, as laryngomalacia can occasionally manifest with severe feeding difficulties or failure to thrive.

How is laryngomalacia diagnosed?

Diagnosis is typically confirmed by a pediatric otolaryngologist using flexible fiberoptic laryngoscopy. During this procedure, the physician visualizes the larynx while the infant is awake to observe the characteristic prolapse of the epiglottis or arytenoid cartilages. Because laryngomalacia can coexist with other airway abnormalities, a thorough evaluation is essential.

What are the key characteristics of laryngomalacia?

Clinical management of laryngomalacia often focuses on observation, but parents should be aware of specific red flags that require immediate medical attention:

• Inspiratory stridor: High-pitched breathing sounds that often worsen when the infant is agitated or feeding.


• Feeding challenges: Difficulty with latching, choking, or prolonged feeding times due to respiratory effort.


• Weight gain issues: Failure to meet expected growth milestones due to the high caloric cost of breathing.


• Apnea or cyanosis: Episodes where the infant stops breathing or turns blue, which require urgent intervention.

Next steps

• Consult a pediatric otolaryngologist for a definitive diagnosis and airway assessment.


• Monitor your child’s weight gain and feeding patterns closely.


• Connect with others on DiseaseMaps.org to share experiences with laryngomalacia.


• Seek emergency care if you notice chest retractions, blue spells, or severe lethargy.
