KA84.2

ICD-11 MMS 2026-01

ABO isoimmunization of fetus or newborn

Description

A condition of the newborn characterized by the destruction of red blood cells initiated by the transmission of anti-A or anti-B antibodies from a mother to the child via the placenta against A or B antigens of the newborn's blood.

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.
