ICD-10 Code K40.01 – Bilateral inguinal hernia, with obstruction, without gangrene, recurrent (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K40.01 – Bilateral inguinal hernia, with obstruction, without gangrene, recurrent
What it is
This code identifies a recurrent hernia on both sides of the groin that is stuck or blocked, but the trapped tissue has not lost blood supply and is not gangrenous. Use it when documentation clearly states bilateral inguinal hernia with obstruction and recurrence.
Clinical signs
Typical findings include a groin bulge, pain, tenderness, and symptoms of bowel obstruction such as nausea, vomiting, or abdominal distention. Clinical features vary; refer to documentation.
When to use this code
Use K40.01 when the provider documents bilateral inguinal hernias, recurrence after prior repair, and current obstruction without gangrene. You should also use it when the record supports obstruction but does not describe strangulation or necrosis. Check documentation if laterality or recurrence is unclear.
Do not use for
Do not use this code for unilateral inguinal hernia, nonrecurrent hernia, or any hernia with gangrene or strangulation. If the record only says “hernia” without obstruction details, check documentation.
Coding tip
Confirm both laterality and recurrence in the note before assigning K40.01.
