ICD-10 Code K44.1 – Diaphragmatic hernia with gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K44.1 – Diaphragmatic hernia with gangrene
What it is
This code identifies a diaphragmatic hernia complicated by gangrene, meaning herniated tissue has lost blood supply and become necrotic. Use it when documentation clearly states gangrene involving the diaphragmatic hernia.
Clinical signs
Clinical features vary; refer to documentation. Findings may include abdominal or chest pain, bowel obstruction, or signs of ischemia when herniated contents are compromised. Confirm that gangrene is explicitly documented.
When to use this code
Use K44.1 when the provider documents diaphragmatic hernia with gangrene, including cases where strangulation has progressed to necrosis. Apply it only when the record supports gangrenous involvement of the herniated tissue. If the note is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for uncomplicated diaphragmatic hernia, reducible hernia, or hernia without gangrene. If the record mentions obstruction or strangulation but not gangrene, choose the code that matches the documented condition.
Coding tip
Code the highest documented severity, but require explicit mention of gangrene before selecting K44.1.
