Transitory ileus of newborn

This code describes a temporary and non-obstructive paralysis of the intestinal muscles in a newborn, leading to a functional blockage of the bowel. It is characterized by abdominal distension, vomiting, and absence of bowel movements, without a physical obstruction. This condition typically resolves spontaneously.

Use this code for newborns presenting with symptoms of intestinal obstruction where diagnostic imaging (e.g., X-ray) confirms the absence of a mechanical blockage and the condition is expected to be transient. Documentation should clearly state "transitory ileus," "paralytic ileus of newborn," or similar terminology indicating a functional, rather than structural, issue.

• Differentiate from mechanical intestinal obstruction (e.g., meconium ileus, atresia), which would require different codes.
• Ensure the documentation specifies "newborn" or "neonatal" to support the use of this age-specific code.
• Consider sequencing this code as a principal diagnosis if it is the primary reason for admission or encounter.
