KA84.0

ICD-11 MMS 2026-01

Rh isoimmunization of fetus or newborn

Description

A condition characterised by the transmission of antibodies from a mother to the child via the placenta against the Rhesus factor of blood. Such antibodies were developed in a Rhesus factor negative mother subsequent to exposure to Rhesus factor positive blood resulting in the break-down of the red blood cells of the fetus.

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.
