Chronic venous hypertension w/o comp of unsp low extrm

This code signifies persistent elevated pressure within the veins of an unspecified lower extremity, not attributed to a known underlying cause (idiopathic) and without any associated complications such as ulceration, inflammation, or varicose veins. It represents a primary venous insufficiency where the venous system is unable to adequately return blood to the heart, leading to chronic venous stasis.

Use this code when documentation indicates chronic venous hypertension of an unspecified lower extremity without any specified complications. This diagnosis is typically supported by clinical findings of edema, skin changes (e.g., hyperpigmentation, lipodermatosclerosis) without ulceration, and/or diagnostic imaging (e.g., duplex ultrasound) confirming venous insufficiency.

• Ensure documentation explicitly states "without complications" or that no complications are present.
• Avoid using this code if specific complications (e.g., ulcer, inflammation, varicose veins) are documented; instead, select a more specific code from the I87.3 series.
• If the affected lower extremity is specified (e.g., right, left), use the appropriate laterality code (I87.301 or I87.302).
