Intestinal obstruction in newborn due to inspissated milk

This code describes an intestinal obstruction occurring in a newborn, specifically caused by the presence of abnormally thick or dried milk within the intestinal lumen. This condition is a form of meconium ileus variant, where the obstruction is due to inspissated milk rather than typical meconium. It leads to symptoms of bowel obstruction in the neonatal period.

Use this code when documentation clearly indicates an intestinal obstruction in a newborn (neonate) and explicitly states the cause is inspissated milk. Supporting documentation would include clinical notes detailing symptoms of bowel obstruction (e.g., abdominal distension, vomiting, failure to pass stool), imaging findings consistent with obstruction, and often, surgical or endoscopic findings confirming inspissated milk as the etiology.

• Differentiate carefully from meconium ileus (777.1), which is due to abnormal meconium, not inspissated milk.
• Ensure the patient's age is documented as newborn or neonate to support the "in newborn" specificity.
• Consider additional codes for any associated congenital anomalies or complications, such as perforation or peritonitis.
