ICD-11 MMS 2026-01

Hydrops fetalis due to haemolytic disease

Description

A fetal condition characterised by an accumulation of fluid or oedema in at least two fetal compartments, including subcutaneous compartments, the pleura, the pericardium, or the abdomen, due to the antibody-mediated break-down of fetal red blood cells.

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.
