ICD-10 Code K44.0 – Diaphragmatic hernia with obstruction, without gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K44.0 – Diaphragmatic hernia with obstruction, without gangrene
What it is
K44.0 identifies a diaphragmatic hernia that is causing bowel or stomach obstruction, but there is no gangrene. Use it when the herniated organ is blocked and tissue death is not documented.
Clinical signs
Typical findings include symptoms of obstruction such as abdominal pain, vomiting, distention, or inability to pass stool or gas. Imaging or operative documentation should support the diaphragmatic hernia and the obstructive component.
When to use this code
Use K44.0 when the record clearly states diaphragmatic hernia with obstruction and specifically excludes gangrene. It may be supported by CT, contrast studies, or surgical findings. If the note only says hernia without obstruction, do not choose this code.
Do not use for
Do not use K44.0 if there is gangrene, because a different code applies. Also avoid it when the documentation describes a diaphragmatic hernia without obstruction or when the type of hernia is not confirmed. Check documentation.
Coding tip
Query the provider if obstruction is mentioned but gangrene status is unclear.
