Secondary vitreoretinal degeneration, bilateral

This code signifies a degenerative condition affecting both the vitreous and retina, occurring as a consequence of another underlying systemic or ocular disease. It indicates structural changes and functional impairment in these posterior segments of the eye that are not primary in nature.

Apply this code when documentation specifies vitreoretinal degeneration in both eyes that is secondary to a pre-existing condition, such as diabetes, high myopia, or inflammatory diseases. The physician's notes must clearly state the secondary nature and bilateral involvement.

• Ensure documentation explicitly states "secondary" and "bilateral" vitreoretinal degeneration.
• Always sequence the underlying cause of the secondary degeneration first, if known and applicable.
• Differentiate from primary vitreoretinal degenerations (e.g., H35.40, H35.41x, H35.42x) which are not caused by another condition.
