Unspecified secondary cataract

This code signifies the presence of a cataract that has developed as a consequence of another ocular or systemic condition, or following eye surgery, where the specific type or cause of the secondary cataract is not documented. It represents a clouding of the lens or lens capsule that is not congenital or age-related primary senile cataract.

Use this code when documentation indicates a secondary cataract but lacks specificity regarding its morphology (e.g., cortical, subcapsular) or underlying cause (e.g., traumatic, inflammatory, drug-induced). This code is appropriate when the physician's notes simply state "secondary cataract" without further detail.

• Always query the provider for more specific documentation regarding the type and cause of the secondary cataract to allow for more precise coding.
• Avoid using this code if a more specific secondary cataract code (e.g., H26.41-H26.49) can be supported by the medical record.
• Code the underlying condition or cause of the secondary cataract first, if known and applicable, followed by this code.
