ICD-10 Code K40.2 – Bilateral inguinal hernia, without obstruction or gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K40.2 – Bilateral inguinal hernia, without obstruction or gangrene
What it is
K40.2 identifies a bilateral inguinal hernia, meaning tissue protrudes through the groin area on both sides. The hernias are present without signs of obstruction or gangrene.
Clinical signs
Typical findings include groin bulges on both sides that may become more noticeable with coughing or straining. Clinical features vary; refer to documentation.
When to use this code
Use K40.2 when the provider documents bilateral inguinal hernias and explicitly states there is no obstruction or gangrene. This applies whether the hernias are reducible or simply present without those complications. Check documentation if laterality or complication status is unclear.
Do not use for
Do not use this code if the hernia is unilateral, recurrent, or complicated by obstruction or gangrene. Also avoid it when the record does not clearly confirm both sides.
Coding tip
Verify laterality and complication status in the operative note, exam, or assessment before assigning K40.2.
