ICD-11 MMS 2026-01

Disorders of muscle tone of newborn

Description

A group of paediatric conditions characterised by abnormal muscle tone in a newborn.

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.
