ICD-10 Code K43 – Ventral hernia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K43 – Ventral hernia
What it is
K43 identifies a ventral hernia, meaning abdominal tissue or bowel pushes through a weakness in the front abdominal wall. Use it when the record documents a ventral, incisional, or other abdominal wall hernia not elsewhere classified.
Clinical signs
Typical findings include a visible or palpable abdominal bulge, discomfort, or pain that may worsen with coughing or straining. Clinical features vary; refer to documentation.
When to use this code
Use K43 when the provider clearly documents a ventral hernia diagnosis, including postoperative or incisional hernias when specified as ventral. Choose the most accurate subcategory if the record identifies obstruction, gangrene, or recurrence. If the note is vague, check documentation before coding.
Do not use for
Do not use K43 for groin, umbilical, or diaphragmatic hernias unless the documentation specifically supports a ventral hernia. Do not assign it when the chart only mentions abdominal pain or a suspected hernia without confirmation.
Coding tip
Match the code to the exact hernia type, site, and complication status documented by the provider.
