ICD-10 Code K40.00 – Bilateral inguinal hernia, with obstruction, without gangrene, not specified as recurrent (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K40.00 – Bilateral inguinal hernia, with obstruction, without gangrene, not specified as recurrent
What it is
This code identifies a bilateral inguinal hernia affecting both groins, with bowel or tissue obstruction but no gangrene. It is used when the hernia is documented as not recurrent.
Clinical signs
Typical findings include groin bulging on both sides, pain, and symptoms of obstruction such as abdominal distention, nausea, or vomiting. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states bilateral inguinal hernia with obstruction and no gangrene. You also need documentation that the hernia is not recurrent. If laterality, obstruction, or recurrence status is unclear, check documentation.
Do not use for
Do not use it for unilateral inguinal hernia, hernia without obstruction, or any hernia with gangrene. Do not assign it if the note does not support bilateral involvement.
Coding tip
Confirm all three elements—bilateral, obstructed, and nonrecurrent—before coding K40.00.
