KA02.4

ICD-11 MMS 2026-01

Fetus or newborn affected by placental transfusion syndromes

Description

Twin-to-twin transfusion syndrome (TTTS) occurs in monozygotic twins while they are in the uterus. It occurs when blood travels from one twin to the other, and the twin that loses blood is the donor twin, while the twin that receives blood is the recipient twin. Depending on the severity of the transfusion, both infants may experience problems, such as anaemia, paleness, and dehydration in the donor twin, and redness and an increased blood pressure in the recipient twin.

Coding note from above levels

These codes are for use when the listed maternal conditions are specified as the cause of confirmed morbidity or potential morbidity which have their origin in the perinatal period (before birth through the first 28 days after birth). Use additional code to identify the condition in the fetus or newborn.

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.
