KA40.1

ICD-11 MMS 2026-01

Cerebral oedema due to birth injury

Description

Cerebral oedema is an excessive accumulation of water in the intracellular or extracellular spaces of the brain. There is a breakdown of the tight endothelial junctions which make up the blood brain barrier.

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.
