Central retinal vein occlusion, unsp, with macular edema

This code signifies a blockage in the central retinal vein, leading to impaired blood flow from the retina, and is complicated by swelling in the macula. This condition affects the central vision and can result in significant vision loss. The "unspecified eye" designation indicates that the laterality of the condition is not documented.

Use this code when the patient's medical record clearly documents central retinal vein occlusion with macular edema, but the specific eye affected (right or left) is not specified. This code is appropriate when the physician's documentation confirms both the vein occlusion and the presence of macular edema, without laterality.

• Avoid using this code if the laterality (right or left eye) is documented; instead, select the more specific code.
• Ensure documentation explicitly states "macular edema" in conjunction with the central retinal vein occlusion.
• Distinguish from branch retinal vein occlusion (H34.83-) which affects a smaller retinal vein.
