ICD-10 Code K41.1 – Bilateral femoral hernia, with gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K41.1 – Bilateral femoral hernia, with gangrene
What it is
This code identifies a femoral hernia on both sides of the groin that has lost blood supply and developed gangrene. It signals a serious incarcerated hernia with tissue death, requiring urgent clinical attention.
Clinical signs
Findings may include painful groin swelling, tenderness, skin changes, and signs of bowel compromise or obstruction. Clinical features vary; refer to documentation for evidence of gangrene and bilateral femoral involvement.
When to use this code
Use K41.1 when the record clearly states bilateral femoral hernia and documents gangrene. Apply it for operative notes, discharge summaries, or specialist assessments that confirm the diagnosis. If laterality or gangrene is unclear, check documentation before coding.
Do not use for
Do not use this code for inguinal, umbilical, or unilateral femoral hernias. It is also wrong when gangrene is not documented or when the note only describes obstruction without tissue death.
Coding tip
Verify both laterality and gangrene in the source record before assigning K41.1.
