Other venous embolism and thrombosis of renal vein

This code signifies the presence of a blood clot (thrombus) or an embolus within the renal vein, affecting the kidney's venous drainage. This condition can lead to impaired kidney function, pain, and potentially kidney damage due to venous congestion.

Use this code when documentation clearly indicates a diagnosis of venous embolism or thrombosis specifically located in the renal vein. Supporting documentation would include imaging reports (e.g., ultrasound, CT angiography, venography) confirming the clot's presence and location, along with physician's diagnostic statements.

• Ensure the documentation specifies "renal vein" to differentiate from other venous thromboses.
• Do not use for arterial thrombosis of the kidney; a different code would apply.
• Consider sequencing this code as a primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity.
