ICD-10 Code K40.20 – Bilateral inguinal hernia, without obstruction or gangrene, not specified as recurrent (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K40.20 – Bilateral inguinal hernia, without obstruction or gangrene, not specified as recurrent
What it is
K40.20 identifies a hernia in both groins where abdominal contents protrude through the inguinal canal, without blockage or tissue death. Use it when the record states bilateral inguinal hernia and does not specify recurrence.
Clinical signs
Typical findings include a groin bulge on both sides, discomfort, or a reducible mass that may become more noticeable with coughing or straining. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents bilateral inguinal hernia and explicitly notes no obstruction or gangrene. It also fits when the hernias are not described as recurrent. If laterality, recurrence, or complication status is unclear, check documentation.
Do not use for
Do not use K40.20 if the hernia is unilateral, recurrent, obstructed, or gangrenous. Do not assign it when the note describes a different groin hernia type or when documentation is incomplete.
Coding tip
Verify all four elements: bilateral, inguinal, no obstruction or gangrene, and not recurrent.
