Meconium obstruction in fetus or newborn

This code signifies an intestinal obstruction in a fetus or newborn caused by abnormally thick or inspissated meconium. This condition can lead to symptoms such as abdominal distension, vomiting, and failure to pass meconium. It is often associated with cystic fibrosis but can occur in other contexts.

Apply this code when documentation confirms a diagnosis of meconium ileus or meconium plug syndrome in a neonate or during fetal assessment. Supporting documentation should include clinical findings, imaging results (e.g., abdominal X-ray showing dilated loops of bowel), and/or surgical findings confirming meconium as the obstructive agent.

• Differentiate from other causes of neonatal intestinal obstruction; ensure meconium is explicitly stated as the etiology.
• If cystic fibrosis is also present, code it as a primary or secondary diagnosis, depending on the sequencing rules and the specific clinical scenario.
• Consider additional codes for any associated complications, such as perforation or peritonitis.
