KB23.2

ICD-11 MMS 2026-01

Respiratory instability of prematurity

Description

Infant within the neonatal period who requires continued respiratory life support, including positive pressure ventilation and/or prolonged oxygen therapy, without a clear pathologic diagnosis. This may be caused by inadequate respiratory muscle strength, excessive chest wall compliance, and/or inadequate CNS respiratory drive.

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.
