Trib rtnl vein occlusion, right eye, with macular edema

This code signifies an obstruction in a smaller branch of the retinal venous system in the right eye, specifically complicated by the presence of macular edema. This occlusion impedes blood flow, leading to fluid leakage and swelling in the macula, the central part of the retina responsible for sharp, detailed vision.

Apply this code when documentation confirms a diagnosis of tributary retinal vein occlusion affecting the right eye, and explicitly states the presence of macular edema. This is typically diagnosed via ophthalmoscopy, fluorescein angiography, and optical coherence tomography (OCT) imaging.

• Ensure documentation specifies "tributary" or "branch" vein occlusion, not central retinal vein occlusion.
• Confirm the laterality is explicitly "right eye" and that macular edema is documented as present.
• Do not use this code if the macular edema is due to a different underlying condition.
