ICD-10 Code K41.4 – Unilateral femoral hernia, with gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K41.4 – Unilateral femoral hernia, with gangrene
What it is
This code identifies a femoral hernia on one side of the groin that has lost blood supply and developed gangrene. It indicates an urgent, severe complication of herniated tissue.
Clinical signs
Expect a painful groin bulge, often below the inguinal ligament, with signs of incarceration or strangulation. Skin changes, tenderness, and systemic illness may appear; clinical features vary, refer to documentation.
When to use this code
Use K41.4 when the record clearly documents a unilateral femoral hernia and gangrene of the herniated contents or surrounding tissue. Code it when the provider specifies the side and the gangrenous complication. If the note only says femoral hernia without gangrene, choose a different code.
Do not use for
Do not use this code for inguinal hernias, bilateral femoral hernias, or uncomplicated femoral hernias. Check documentation if the record mentions obstruction or incarceration without gangrene.
Coding tip
Verify both laterality and gangrene in the operative note or assessment before assigning K41.4.
