Meconium plug without ileus

Description

Meconium plug, also referred to as functional immaturity of the colon, is an obstruction in the newborn colon. It is usually a transient disorder of the newborn and is characterised by delayed passage of meconium and intestinal dilatation.

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.
