ICD-11 MMS 2026-01

Certain specified transitory neonatal electrolyte or metabolic disturbances

Description

A group of paediatric conditions in which there is a temporary abnormality in the normal processes of enzyme catalyzed reactions within tissue cells (metabolism) or with the levels of minerals in the blood or other body fluids.

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.
