ICD-10 Code K40.10 – Bilateral inguinal hernia, with gangrene, not specified as recurrent (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K40.10 – Bilateral inguinal hernia, with gangrene, not specified as recurrent
What it is
This code identifies a bilateral inguinal hernia affecting both groins, with gangrene present. Use it when the documentation specifies inguinal hernias on both sides and tissue necrosis, without stating that the hernia is recurrent.
Clinical signs
Findings may include groin bulges, pain, tenderness, and signs of incarcerated or strangulated hernia. Gangrene suggests compromised blood supply and tissue death; clinical features vary, so refer to documentation.
When to use this code
Use K40.10 when the provider documents bilateral inguinal hernia with gangrene and does not describe it as recurrent. It also fits operative, imaging, or discharge documentation that clearly supports both laterality and gangrenous complication. Check documentation if the record is incomplete.
Do not use for
Do not use this code for unilateral inguinal hernia, non-gangrenous hernia, or recurrent hernia. If laterality or gangrene is not documented, select a more specific or unspecified code only when supported by the record.
Coding tip
Confirm both sides and the presence of gangrene before assigning K40.10.
