Retinal telangiectasis, right eye

This code signifies an abnormal dilation and tortuosity of the retinal blood vessels in the right eye. This vascular anomaly can lead to leakage, hemorrhage, and exudation within the retina, potentially affecting vision. It is a non-proliferative retinopathy characterized by telangiectatic vessels.

Use this code when documentation explicitly states retinal telangiectasis affecting the right eye. This diagnosis is typically made during an ophthalmologic examination, often supported by imaging such as fluorescein angiography or optical coherence tomography (OCT) that visualizes the abnormal vessels.

• Ensure laterality is clearly documented as right eye; separate codes exist for the left and bilateral involvement.
• Distinguish from other retinal vascular disorders like diabetic retinopathy or retinal vein occlusion, which have distinct ICD-10-CM codes.
• Look for associated conditions such as macular edema or exudates, which may require additional coding.
