ICD-10 Code K43.2 – Incisional hernia without obstruction or gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K43.2 – Incisional hernia without obstruction or gangrene
What it is
K43.2 identifies an incisional hernia that develops through a prior surgical scar. The hernia is present, but there is no documented bowel obstruction or gangrene.
Clinical signs
Typical findings include a visible or palpable bulge at or near an old incision, often more noticeable with coughing or straining. Clinical features vary; refer to documentation.
When to use this code
Use K43.2 when the record clearly states an incisional hernia and does not mention obstruction or gangrene. You may also use it when the provider documents a reducible or uncomplicated postoperative hernia. If the note is vague about complications, check documentation before coding.
Do not use for
Do not use this code if the hernia is described as obstructed or gangrenous, because those conditions require a different ICD-10-CM code. Also avoid it for other abdominal wall hernias that are not incisional.
Coding tip
Match the code to the provider’s exact wording and complication status; if obstruction or gangrene is not explicitly ruled out, verify the record.
