Other secondary cataract, unspecified eye

This code signifies a cataract that develops as a consequence of another eye condition, systemic disease, or medication, where the specific type of secondary cataract is not further specified. It indicates clouding of the lens that is not congenital, senile, or traumatic in origin, and affects an unspecified eye.

Apply this code when documentation clearly states "secondary cataract" without further detail on the specific type (e.g., posterior subcapsular, complicated) and the affected eye is not specified. This is appropriate when the underlying cause of the secondary cataract is known but the cataract's morphology isn't precisely documented.

• Avoid using this code if a more specific secondary cataract code (e.g., H26.1x for traumatic, H26.2x for complicated) can be assigned.
• Always attempt to clarify the specific type of secondary cataract and the affected eye (right, left, bilateral) with the provider to allow for more precise coding.
• Code the underlying cause of the secondary cataract (e.g., diabetes, uveitis) in addition to this code.
