Chronic venous htn w ulcer and inflam 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, which has led to the development of skin ulceration and associated inflammation. It describes a severe manifestation of chronic venous insufficiency affecting both legs.

Apply this code when documentation clearly indicates chronic venous hypertension affecting both lower limbs, specified as idiopathic, with evidence of both ulceration and inflammation. This typically presents as non-healing wounds and erythema/swelling in the ankle or lower leg region of both legs.

• Ensure documentation explicitly states "idiopathic" or that no secondary cause for the venous hypertension is identified.
• Verify that both ulceration and inflammation are present and documented for both lower extremities.
• Do not use if the venous hypertension is due to a known cause (e.g., post-thrombotic syndrome); instead, use a more specific code from the I87.0- series.
