ICD-10 Code K56.690 – Other partial intestinal obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K56.690 – Other partial intestinal obstruction
What it is
K56.690 identifies a partial blockage of the intestine that does not fit a more specific obstruction code. It means intestinal contents can still pass, but flow is reduced.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include abdominal pain, distention, nausea, vomiting, and decreased bowel function, but the chart must support a partial obstruction.
When to use this code
Use this code when the provider documents a partial intestinal obstruction and does not specify a more precise site or cause. It also fits cases described as other partial obstruction after evaluation. Check documentation for the affected bowel segment and whether the condition is partial rather than complete.
Do not use for
Do not use K56.690 for complete intestinal obstruction or for paralytic ileus. If the record identifies a more specific intestinal obstruction code, report that code instead.
Coding tip
Confirm the note says “partial” and “intestinal obstruction”; if the wording is vague, query the provider or check documentation.
