KB21.0

ICD-11 MMS 2026-01

Severe birth asphyxia

Description

Pulse less than 100 per minute at birth and falling or steady, respiration absent or gasping, colour poor, tone absent.

Coding note from above levels

This category is not to be used for low Apgar score without mention of asphyxia or other respiratory problems.

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.
