KB87.2ICD-11 MMS 2026-01
Meconium ileus without perforation
Description
The meconium sometimes becomes thickened and congested in the terminal ileum, a condition known as meconium ileus. Meconium ileus is among the most common causes of intestinal obstruction in the newborn, accounting for 9-33% of neonatal intestinal obstructions. A symptom of both Hirschsprung’s disease and cystic fibrosis is the failure to pass meconium. Some babies have a blockage in their colon that may look like meconium ileus (a meconium plug), and they have small left colon syndrome. This means the last part of their colon is smaller than normal.
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.
