ICD-10 Code K41.21 – Bilateral femoral hernia, without obstruction or gangrene, recurrent (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K41.21 – Bilateral femoral hernia, without obstruction or gangrene, recurrent
What it is
This code identifies a recurrent femoral hernia on both sides of the groin, with no obstruction or gangrene. It means the hernia has returned after prior repair or prior presence and is currently not strangulated.
Clinical signs
Patients may have a groin bulge, discomfort, or pain that worsens with standing, coughing, or lifting. Clinical features vary; refer to documentation for laterality, recurrence, and whether obstruction or gangrene is absent.
When to use this code
Use this code when the record clearly documents bilateral femoral hernias and states they are recurrent. The documentation should also indicate there is no obstruction and no gangrene. If the note does not confirm recurrence or both sides, check documentation before coding.
Do not use for
Do not use this code for unilateral femoral hernia, inguinal hernia, or a femoral hernia with obstruction or gangrene. Do not assign it if recurrence is not documented.
Coding tip
Verify all three elements together: bilateral, recurrent, and without obstruction or gangrene.
