Intestinal adhesions [bands], with partial obstruction

This code describes a condition where fibrous bands of scar tissue (adhesions) form within the abdominal cavity, specifically involving the intestines, leading to a partial blockage of the intestinal lumen. This partial obstruction impairs the normal passage of digestive contents, causing symptoms such as abdominal pain, distension, nausea, and vomiting.

Use this code when documentation clearly indicates the presence of intestinal adhesions that are causing a partial obstruction. This is often seen in patients with a history of abdominal surgery, inflammation, or infection. Supporting documentation should specify both the adhesions and the resulting partial obstruction.

• Ensure documentation explicitly states "partial obstruction" due to adhesions; do not assume partial if not specified.
• Distinguish from complete intestinal obstruction (K56.6-), which is a separate and more severe condition.
• Consider sequencing this code as a principal diagnosis if it is the primary reason for the encounter, or as a secondary diagnosis if it is a comorbidity affecting treatment.
