Central retinal vein occls, right eye, with macular edema

This code signifies a blockage of the main vein draining blood from the retina in the right eye, specifically complicated by swelling of the macula, the central part of the retina responsible for sharp, detailed vision. This occlusion impedes blood flow, leading to hemorrhage and fluid leakage within the retina, and the macular edema further compromises visual acuity.

Use this code when documentation clearly indicates a diagnosis of central retinal vein occlusion affecting the right eye, and explicitly states the presence of macular edema. This typically follows ophthalmoscopic examination, fluorescein angiography, or optical coherence tomography (OCT) confirming both the occlusion and the macular swelling.

• Ensure documentation specifies "central" retinal vein occlusion versus a branch retinal vein occlusion.
• Verify the laterality (right eye) and the presence of macular edema are explicitly stated.
• Do not use this code if macular edema is not documented, even if the central retinal vein occlusion is present.
