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

This code describes a condition where a smaller vein in the retina of the left eye is blocked, leading to impaired blood flow and potential vision loss. The "stable" designation indicates that the condition is not actively worsening or improving at the time of assessment.

Use this code when documentation confirms a diagnosis of a tributary retinal vein occlusion affecting the left eye, and the physician explicitly states the condition is stable. This typically applies to follow-up visits after initial diagnosis and treatment, or when the occlusion has resolved but left residual effects.

• Ensure documentation specifies "tributary" or "branch" and not central retinal vein occlusion.
• Verify the laterality is clearly documented as "left eye."
• Confirm the "stable" status; if active or resolving, a different subcategory code would be appropriate.
