ICD-10 Code K40.11 – Bilateral inguinal hernia, with gangrene, recurrent (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K40.11 – Bilateral inguinal hernia, with gangrene, recurrent
What it is
This code identifies a recurrent inguinal hernia on both sides of the groin with gangrenous tissue. Use it when the documentation clearly states bilateral inguinal hernia, gangrene, and recurrence.
Clinical signs
Clinical features vary; refer to documentation. Findings may include groin bulge, pain, tenderness, and signs of compromised tissue when gangrene is present.
When to use this code
Use K40.11 when the provider documents a bilateral inguinal hernia that has come back after prior repair and includes gangrene. The record should support both the bilateral location and the recurrent nature. If the note does not specify gangrene or recurrence, check documentation before assigning this code.
Do not use for
Do not use this code for unilateral inguinal hernia, nonrecurrent hernia, or hernia without gangrene. Check documentation if the site is femoral, ventral, or otherwise different.
Coding tip
Confirm laterality, recurrence, and gangrene in the same encounter note before coding K40.11.
