ICD-10 Code K56.50 – Intestinal adhesions [bands], unspecified as to partial versus complete obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K56.50 – Intestinal adhesions [bands], unspecified as to partial versus complete obstruction
What it is
K56.50 identifies intestinal adhesions or bands causing obstruction, when the record does not specify whether the blockage is partial or complete. Use it for adhesive bowel obstruction documented without further detail.
Clinical signs
Clinical features vary; refer to documentation. Commonly, adhesive obstruction is described with abdominal pain, distention, vomiting, and reduced passage of stool or gas, but the chart should support the diagnosis.
When to use this code
Use this code when the provider documents intestinal adhesions or bands with bowel obstruction, but does not state partial versus complete. It also fits cases where imaging or operative notes confirm adhesive obstruction and the degree of obstruction remains unspecified. Check documentation for laterality or other more specific terms.
Do not use for
Do not use this code if the record clearly states partial or complete obstruction and a more specific code is available. Avoid it for non-adhesive intestinal obstruction or when the diagnosis is not confirmed. Check documentation.
Coding tip
Code from the most specific obstruction wording in the note, and query if adhesions are mentioned but obstruction type is unclear.
