KB2A.1

ICD-11 MMS 2026-01

Obstructive neonatal apnoea

Description

Apnoea that occurs secondary to diminished airway airflow from an obstruction in the airway from the nose and mouth, tongue, hypopharynx, epiglottis, vocal cords or subglottic region. This is characterised by initial increased work of breathing and rapid progression to cyanosis.

Coding note from above levels

Conditions arising in the perinatal period, even though death or morbidity occurs later, should, as far as possible, be coded to chapter 19, which takes precedence over chapters containing codes for diseases by their anatomical site. For children less than 28 days old, assume that a reported condition developed in the perinatal period, unless the duration is stated and the onset was after the first completed week of life.
