In simple words: This code describes a long-term condition where the veins in your legs don't efficiently return blood to the heart, causing blood to pool in the legs.

Venous insufficiency (chronic) (peripheral).It is characterized by pooling of blood in the veins of the legs due to incompetent venous valves or venous obstruction, leading to symptoms like swelling, pain, and skin changes.  Code also, if applicable, associated hypertensive conditions such as essential (primary) hypertension (I10), hypertensive chronic kidney disease (I12.-), hypertensive heart and chronic kidney disease (I13.-), hypertensive heart disease (I11.-). Use additional code, if applicable, to specify site and severity of ulcer (L97.-).

Example 1: A patient presents with leg swelling, aching, and varicose veins, diagnosed with chronic venous insufficiency., A patient with a history of deep vein thrombosis develops chronic venous insufficiency and a venous stasis ulcer., A patient experiences leg pain and skin discoloration, diagnosed with chronic venous insufficiency due to venous valve dysfunction.

Detailed clinical findings such as leg swelling, pain, skin changes (e.g., discoloration, thickening, or ulceration), and results of diagnostic tests like venous duplex ultrasound are essential for accurate coding.
