KA61.1

ICD-11 MMS 2026-01

Neonatal listeriosis

Description

A condition affecting fetuses or neonates, caused by an infection with the gram-positive bacteria Listeria. This condition is characterised by respiratory distress in the neonate, by stillbirth, or by abortion. Transmission is by vertical transmission. Confirmation is by identification of Listeria in the neonate and mother.

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.
