Chronic venous hypertension w ulcer of bilateral low extrm

This code signifies a long-standing elevation of venous pressure in both lower extremities, not attributable to a specific underlying cause (idiopathic), which has resulted in the formation of open sores or breaks in the skin. This condition is characterized by impaired venous return leading to skin changes and ulceration.

Apply this code when documentation clearly indicates chronic venous hypertension affecting both legs, with the presence of ulcers, and no specific secondary cause (e.g., deep vein thrombosis) is identified. Supporting documentation includes physician notes detailing bilateral lower extremity ulcers, signs of chronic venous insufficiency, and a diagnosis of idiopathic venous hypertension.

• Ensure documentation specifies "idiopathic" or "primary" to differentiate from secondary venous hypertension.
• Verify that ulcers are present on both lower extremities; separate codes exist for unilateral involvement.
• Do not use this code if the venous hypertension is due to a known cause, such as post-thrombotic syndrome.
