Chronic venous hypertension w ulcer of l low extrem

This code signifies a persistent elevation of venous pressure in the left lower extremity, not attributable to a specific underlying cause, which has resulted in the formation of an open sore or lesion. This condition is characterized by impaired venous return, leading to tissue damage and ulceration.

Apply this code when documentation clearly indicates chronic venous insufficiency of the left leg with an idiopathic etiology and the presence of an ulcer. Supporting documentation should include physician notes detailing the chronicity, laterality, and the presence of an open wound consistent with a venous ulcer.

• Always confirm laterality (left lower extremity) is explicitly documented.
• Ensure the ulcer is directly attributed to the chronic venous hypertension; do not use for ulcers of other etiologies.
• Consider additional codes for the severity or specific type of ulcer, if documented (e.g., non-pressure chronic ulcer codes).
