Secondary vitreoretinal degeneration, unspecified eye

This code signifies a degenerative process affecting both the vitreous and retina, which is a consequence of another underlying ocular or systemic condition. It indicates a breakdown or deterioration of these structures, leading to potential visual impairment. The "unspecified eye" designation means the laterality of the condition is not documented.

Use this code when documentation clearly states "secondary vitreoretinal degeneration" but does not specify whether it affects the right or left eye. This often occurs when the physician notes the condition generally without laterality, or when the medical record is incomplete regarding the affected eye. It requires an additional code for the underlying cause.

• Always sequence the underlying cause of the secondary degeneration first.
• Avoid using this code if laterality (right or left eye) is documented; instead, use H35.461 or H35.462.
• Ensure the documentation supports the "secondary" nature of the degeneration, differentiating it from primary vitreoretinal degenerations (H35.40-H35.45).
