Chronic venous hypertension w ulcer of r low extrem

This code signifies a persistent elevation of venous pressure in the right lower extremity, not attributable to a secondary cause, which has led to the formation of an open sore or ulcer. This condition is characterized by impaired venous return, often resulting in skin changes, edema, and ultimately tissue breakdown.

Apply this code when documentation clearly indicates a chronic, idiopathic venous hypertension affecting the right lower limb, specifically noting the presence of an ulcer. This is typically seen in patients with long-standing venous insufficiency where the underlying cause is not identified as a specific thrombus or other secondary condition.

• Ensure documentation specifies "idiopathic" or "primary" venous hypertension to differentiate from secondary causes.
• Verify the laterality (right lower extremity) is explicitly stated in the medical record.
• Do not use this code if the ulcer is due to arterial insufficiency, diabetic neuropathy, or pressure.
