Perinatal intestinal perforation

This code signifies a hole or tear in the intestinal wall of a newborn or fetus, occurring during the perinatal period. This can lead to leakage of intestinal contents into the abdominal cavity, potentially causing peritonitis and sepsis. It represents a serious gastrointestinal emergency in neonates.

Apply this code when documentation confirms a diagnosis of intestinal perforation in a neonate, typically identified through imaging studies (e.g., abdominal X-ray showing pneumoperitoneum) or surgical exploration. This condition is often associated with necrotizing enterocolitis (NEC) or meconium peritonitis.

• Differentiate from congenital malformations of the intestine that may also present with perforation.
• Always code any underlying cause, such as necrotizing enterocolitis (K55.0-), if documented.
• Ensure the documentation specifies the perinatal period to support this code.
