ICD-10 code for liver venous thrombosis

The ICD-10-CM code for liver venous thrombosis is I82.0 (Budd-Chiari syndrome). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on I82.0.

Related codes cover thrombophlebitis migrans (I82.1), embolism and thrombosis of vena cava and other thoracic veins (I82.2), embolism and thrombosis of renal vein (I82.3), acute embolism and thrombosis of deep veins of lower extremity (I82.4), chronic embolism and thrombosis of deep veins of lower extremity (I82.5), acute embolism and thrombosis of veins of upper extremity (I82.6), chronic embolism and thrombosis of veins of upper extremity (I82.7), embolism and thrombosis of other specified veins (I82.8) and 4 more.
