ICD-10 Code K56.2 – Volvulus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K56.2 – Volvulus
What it is
K56.2 identifies volvulus, a twisting of part of the intestine that can block the bowel and reduce blood flow. Use it when the record clearly documents volvulus without a more specific site or complication code.
Clinical signs
Typical findings include abdominal pain, distention, vomiting, and signs of bowel obstruction. Clinical features vary; refer to documentation for the affected segment and whether ischemia or perforation is present.
When to use this code
Use K56.2 when the provider documents volvulus as the diagnosis and does not specify a more detailed code. It may appear in emergency, inpatient, or surgical records describing intestinal twisting or obstruction. Confirm the note identifies volvulus, not only nonspecific abdominal pain or obstruction.
Do not use for
Do not use this code for simple constipation, ileus, or bowel obstruction without volvulus. Check documentation if the record instead describes intussusception, hernia-related obstruction, or a different gastrointestinal disorder.
Coding tip
Look for the exact term “volvulus” in the provider assessment and code any documented site-specific or complication codes separately when supported.
