What K43 covers · when clinicians use it
ICD-10 code K43 identifies Ventral hernia in the U.S. ICD-10-CM clinical and billing record set. It sits within the Digestive System chapter (K00–K95), the section that groups related diagnoses so providers, payers, and public-health agencies report them consistently. Clinicians and medical coders apply K43 when an encounter's findings match the Ventral hernia description, attaching it to the patient record so downstream insurance claims, payer audits, quality reporting, and epidemiological surveillance all reference the same standardized diagnosis. The ICD-10-CM is maintained by the Centers for Medicare & Medicaid Services and the CDC's National Center for Health Statistics, with an updated official code set released each U.S. fiscal year — always verify K43 against the current CMS/CDC release and your payer's documentation guidance before final use. This page summarizes documentation context for K43 and is a coding reference, not clinical, diagnostic, or billing advice.
K43 refers to Ventral hernia, a protrusion of an organ or tissue through an abnormal opening in the abdominal wall or diaphragm. Hernias may be reducible or incarcerated and can cause pain, bowel obstruction, or other complications if not treated.
Symptoms
- Visible bulge in the abdomen or groin – Often more prominent when standing or straining
- Pain or discomfort – Especially during physical activity or lifting
- Pressure or heaviness – Common in larger or chronic hernias
- Nausea or vomiting – May indicate bowel obstruction in complicated cases
- Acid reflux or chest pain – Seen in diaphragmatic hernia (K44)
Diagnosis
Diagnosis of Ventral hernia is usually clinical through physical examination. Imaging such as ultrasound, CT scan, or MRI may be used to confirm location, size, or complications, especially in obese patients or for internal hernias.
ICD10 Code Usage
ICD10 code K43 is used by surgeons, emergency physicians, and general practitioners. It supports surgical scheduling (herniorrhaphy), documentation of complications, and hospital billing for both elective and emergency hernia repair procedures.

FAQs
Q1: What is ICD10 code K43?
A: It refers to Ventral hernia, a condition where abdominal contents protrude through a weakened or abnormal opening in the abdominal wall or diaphragm.
Q2: What’s the difference between K40 and K41?
A: K40 refers to inguinal hernias (common in men), while K41 refers to femoral hernias (more common in women, and higher risk of strangulation).
Q3: Are umbilical (K42) and ventral (K43) hernias related?
A: Both are abdominal wall hernias but occur in different locations—umbilical at the belly button and ventral through previous surgical sites or weakened areas.
Q4: What does K46 cover?
A: K46 is used when the hernia type is not specified in clinical records or diagnosis.
Q5: Who manages these conditions?
A: General surgeons primarily manage hernias, with support from radiologists for imaging and emergency teams for complicated cases.
Conclusion
ICD10 code K43 ensures accurate diagnosis and management of Ventral hernia, supporting surgical decision-making, timely interventions, and effective documentation in both outpatient and emergency care settings.
