ICD-10 Code K45.1 – Other specified abdominal hernia with gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K45.1 – Other specified abdominal hernia with gangrene
What it is
K45.1 identifies an abdominal hernia in an other specified site when the herniated tissue has gangrene. Use this code when the record documents necrosis or gangrenous change in the hernia contents.
Clinical signs
Clinical features vary; refer to documentation. Gangrene may be noted with a painful, irreducible hernia and signs of compromised tissue, but coding depends on the provider’s documented diagnosis.
When to use this code
Use K45.1 when the clinician clearly documents an abdominal hernia at an unspecified or other specified site and states that gangrene is present. This applies whether the diagnosis appears in an operative note, discharge summary, or problem list. If the site or complication is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for abdominal hernias without gangrene, or when the record describes a different hernia type with its own code. If the documentation does not support gangrene, choose the more accurate hernia code.
Coding tip
Confirm both elements: the hernia site is “other specified abdominal” and gangrene is explicitly documented.
