Tributary (branch) retinal vein occlusion, right eye, stable

This code signifies a stable blockage in a smaller vein branching off the main retinal vein in the right eye. This occlusion impedes blood flow from the retina, potentially leading to fluid leakage and vision impairment. "Stable" indicates that the condition is not actively worsening or undergoing acute changes.

Use this code for a patient with a documented history of tributary retinal vein occlusion in the right eye where the condition is currently stable, without acute symptoms or progression. Supporting documentation should include ophthalmological examination findings confirming the diagnosis and the stable nature of the occlusion, often following initial treatment or observation.

• Differentiate from acute or progressive occlusions; those require different codes.
• Ensure laterality (right eye) is clearly documented.
• Confirm the specific type of vein occlusion (tributary/branch vs. central) to avoid miscoding.
