Intestinal adhesions [bands] with complete obstruction

This code signifies a condition where fibrous bands of tissue, known as adhesions, have formed within the abdominal cavity, leading to a total blockage of the intestinal tract. This complete obstruction prevents the passage of food, fluid, and gas through the intestines. It is a serious complication often resulting from previous abdominal surgery, inflammation, or infection.

Apply this code when documentation clearly indicates the presence of intestinal adhesions causing a complete obstruction. This diagnosis is typically supported by imaging studies (e.g., CT scan showing a transition point with proximal dilation and distal collapse) and clinical signs/symptoms of complete bowel obstruction (e.g., obstipation, severe abdominal pain, vomiting).

• Ensure documentation explicitly states "complete obstruction" to differentiate from partial obstruction.
• Do not use this code if the obstruction is due to a hernia or other specified cause; look for more specific codes.
• Consider sequencing this code as the principal diagnosis if it is the primary reason for the encounter and treatment.
