Cataract secondary to ocular disorders, bilateral

This code signifies the presence of cataracts in both eyes that have developed as a consequence of another pre-existing ocular condition, specifically those of a degenerative or inflammatory nature. This indicates a secondary cataract formation rather than an age-related or traumatic origin.

Use this code when documentation clearly states bilateral cataracts resulting from an underlying degenerative eye disease (e.g., retinitis pigmentosa, high myopia) or an inflammatory eye condition (e.g., chronic uveitis, iridocyclitis). Physician notes should explicitly link the cataract development to the primary ocular disorder.

• Always sequence the underlying ocular disorder (e.g., H35.52 for retinitis pigmentosa, H20.00 for acute iridocyclitis) before this code.
• Distinguish from age-related cataracts (H25.xx) or traumatic cataracts (H26.1x) which have different etiologies.
• Ensure documentation specifies "bilateral" and clearly identifies the degenerative or inflammatory nature of the causative ocular disorder.
