Budd-chiari syndrome

This code represents Budd-Chiari syndrome, a rare condition characterized by obstruction of hepatic venous outflow, typically at the level of the hepatic veins or the inferior vena cava. This obstruction leads to congestion of the liver, portal hypertension, and can result in liver damage and cirrhosis.

Use this code when documentation clearly indicates a diagnosis of Budd-Chiari syndrome. This diagnosis is often supported by imaging studies (e.g., Doppler ultrasound, CT, MRI) showing hepatic vein occlusion or stenosis, liver biopsy findings, and clinical signs of liver congestion.

• Ensure documentation specifies the cause of the obstruction if known, as this may impact other associated codes.
• Distinguish from other causes of portal hypertension or liver disease; Budd-Chiari syndrome is specific to hepatic venous outflow obstruction.
• Code any underlying conditions contributing to Budd-Chiari syndrome (e.g., hypercoagulable states) as additional diagnoses.
