ICD-10 Code K46.0 – Unspecified abdominal hernia with obstruction, without gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K46.0 – Unspecified abdominal hernia with obstruction, without gangrene
What it is
K46.0 identifies an abdominal hernia that is causing obstruction, but there is no gangrene. Use it when the hernia site is not further specified and the bowel or other contents are blocked.
Clinical signs
Typical findings include a painful, irreducible hernia with abdominal distention, nausea, vomiting, or decreased bowel function. Clinical features vary; refer to documentation.
When to use this code
Use K46.0 when the record documents an abdominal hernia with obstruction and does not identify the exact hernia type or location. It also applies when the provider states there is no gangrene. If the site is specified, choose the more specific code instead.
Do not use for
Do not use this code for hernias without obstruction or for hernias with gangrene. Do not assign it when documentation identifies a more specific abdominal hernia category.
Coding tip
Check the note for obstruction and absence of gangrene before coding, and code the most specific hernia type available.
