Chronic venous hypertension w/o comp of l low extrem

This code signifies persistent elevated venous pressure in the left lower extremity, not attributed to a specific underlying cause (idiopathic), and without any associated skin changes, ulceration, or other complications. It describes a chronic condition of impaired venous return in the left leg.

Apply this code when documentation explicitly states "chronic venous hypertension" or "venous insufficiency" of the left lower extremity, and specifically notes it as idiopathic or primary, with no mention of complications such as edema, dermatitis, or ulceration. This code is appropriate when the physician has ruled out secondary causes and confirmed the absence of complications.

• Ensure documentation specifies "left lower extremity" and the absence of complications.
• Distinguish from codes for venous insufficiency with complications (e.g., edema, ulceration), which require more specific codes.
• Do not use if a specific cause for the venous hypertension (e.g., post-thrombotic syndrome) is identified; instead, code the underlying cause.
