ICD-10 Code K41.31 – Unilateral femoral hernia, with obstruction, without gangrene, recurrent (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K41.31 – Unilateral femoral hernia, with obstruction, without gangrene, recurrent
What it is
K41.31 identifies a recurrent femoral hernia on one side that is obstructed but has no gangrene. Use it when bowel or tissue is trapped in the femoral canal and blood supply is not documented as lost.
Clinical signs
Typical findings include a groin bulge below the inguinal ligament, pain, and symptoms of obstruction such as nausea, vomiting, or abdominal distention. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states a unilateral femoral hernia, recurrence, and obstruction, but no gangrene. It fits postoperative or repeat presentations if the provider documents the hernia as recurrent. Check documentation when laterality or obstruction is unclear.
Do not use for
Do not use this code for femoral hernia without obstruction, with gangrene, or when the hernia is not documented as recurrent. Do not assign it if the site is inguinal or the side is unspecified.
Coding tip
Confirm laterality, recurrence, and the presence of obstruction in the note before assigning K41.31.
