ICD-10 Code K41.91 – Unilateral femoral hernia, without obstruction or gangrene, recurrent (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K41.91 – Unilateral femoral hernia, without obstruction or gangrene, recurrent
What it is
This code identifies a recurrent femoral hernia on one side, with no obstruction and no gangrene. It means abdominal contents have protruded through the femoral canal and the hernia has come back after prior repair or resolution.
Clinical signs
Typical findings include a groin or upper thigh bulge, discomfort, or a reducible mass below the inguinal ligament. Clinical features vary; refer to documentation.
When to use this code
Use K41.91 when the record clearly states a unilateral femoral hernia that is recurrent and not currently obstructed or gangrenous. This is appropriate after prior repair, when the same-side hernia returns. Check documentation if laterality or recurrence is unclear.
Do not use for
Do not use this code for femoral hernias with obstruction or gangrene, or for nonrecurrent femoral hernias. Do not substitute it for inguinal hernias or unspecified groin hernias.
Coding tip
Confirm laterality, recurrence, and absence of obstruction or gangrene in the provider note before assigning K41.91.
