CB04.2

ICD-11 MMS 2026-01

Disorders of surfactant metabolism

Description

Primary interstitial lung disease specific to childhood due to pulmonary surfactant protein anomalies is a group of interstitial lung diseases (ILD) induced by genetic mutations disrupting surfactant function and gas exchange in the lung. The disorders caused by these mutations affect full-term infants and older children and exhibit considerable overlap in their clinical and histologic presentation
