ICD-11 MMS 2026-01

Congenital lung or lobar atelectasis

Description

Collapsed lobe or lobes of the lung that is present at birth and is due to narrowing of the airway, kinking of the airway, compression from a mass in the airway or other congenital abnormality.

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.
