Venous engorgement, bilateral

This code signifies a condition where the veins in both eyes are abnormally distended or swollen, often due to increased intravascular pressure or impaired venous outflow. It indicates a bilateral presentation of ocular venous congestion, which can be a sign of underlying systemic or localized pathology.

Use this code when documentation clearly states "venous engorgement" affecting both eyes. This often accompanies conditions like central retinal vein occlusion, papilledema, or orbital tumors. Supporting documentation should include ophthalmological exam findings noting dilated, tortuous, or congested retinal veins in both eyes.

• Ensure the documentation explicitly states "bilateral" involvement; otherwise, a unilateral or unspecified code may be more appropriate.
• Always code the underlying cause of the venous engorgement first, if known and documented (e.g., central retinal vein occlusion).
• Differentiate from other vascular abnormalities like arterial narrowing or microaneurysms, which have distinct codes.
