KA21.40

ICD-11 MMS 2026-01

Preterm newborn, gestational age 28 completed weeks

Description

Preterm newborn, gestational age 28 weeks, 0 days through 28 weeks, 6 days

Coding note

When both birth weight and gestational age are available, priority of assignment should be given to birth weight.

Coding note from above levels

When both birth weight and gestational age are available, priority of assignment must be given to gestational age.

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.
