Paralytic ileus

This code signifies a functional obstruction of the intestines caused by a lack of peristalsis, rather than a physical blockage. It results in the accumulation of gas and fluid within the bowel, leading to abdominal distension, pain, and vomiting. This condition often arises as a complication of surgery, medications, or severe illness.

Assign this code when documentation clearly indicates a diagnosis of paralytic ileus, also known as adynamic ileus. This is commonly seen post-operatively, after trauma, or in patients with electrolyte imbalances or sepsis. Supporting documentation should specify the absence of a mechanical obstruction.

• Differentiate from mechanical intestinal obstruction (e.g., due to adhesions, hernia, or tumor), which requires different codes.
• Consider sequencing if the paralytic ileus is a complication of another condition or procedure; the underlying cause may be primary.
• Ensure the medical record explicitly states "paralytic ileus" or "adynamic ileus" to support this diagnosis.
