Cataract secondary to ocular disorders, right eye

This code signifies a cataract that has developed in the right eye as a consequence of another pre-existing ocular condition, such as a degenerative eye disease (e.g., retinitis pigmentosa) or an inflammatory eye disease (e.g., uveitis). The cataract is not age-related or due to trauma, but rather a secondary complication of the underlying eye disorder.

Apply this code when documentation clearly indicates a cataract in the right eye resulting from a specified degenerative or inflammatory ocular condition. The medical record should explicitly link the cataract's etiology to the primary eye disorder, rather than attributing it to age or other causes.

• Always code the underlying ocular disorder first, followed by this code for the secondary cataract.
• Ensure the documentation specifies "right eye" for laterality; otherwise, an unspecified laterality code may be more appropriate.
• Distinguish from age-related cataracts (H25.-) or traumatic cataracts (H26.1-), which have different etiologies.
