ICD-10 Code K43.5 – Parastomal hernia without obstruction or gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K43.5 – Parastomal hernia without obstruction or gangrene
What it is
This code identifies a hernia that develops beside a stoma, where abdominal contents bulge through the abdominal wall. It applies when there is no bowel obstruction and no gangrene.
Clinical signs
Typical findings include a visible or palpable bulge near the stoma, discomfort, or appliance fit problems. Clinical features vary; refer to documentation.
When to use this code
Use K43.5 when the provider documents a parastomal hernia and specifically states there is no obstruction or gangrene. It also fits follow-up visits, imaging impressions, or surgical evaluations that confirm the hernia without acute complication.
Do not use for
Do not use this code if the record documents obstruction or gangrene, since those require different coding. Also avoid it when the hernia is not parastomal or the documentation is unclear.
Coding tip
Check the note for laterality, complication status, and whether the hernia is truly parastomal before assigning K43.5.
