Unspecified infantile and juvenile cataract, left eye

This code signifies the presence of a cataract in the left eye of a pediatric patient (infant or juvenile) where the specific type or cause of the cataract has not been determined or documented. It indicates opacification of the lens, leading to impaired vision, without further etiological detail.

Apply this code when the medical record clearly states a diagnosis of infantile or juvenile cataract affecting the left eye, but lacks information regarding its specific morphology (e.g., cortical, nuclear, subcapsular) or underlying cause (e.g., congenital, traumatic, metabolic). Documentation should confirm the patient's age falls within the pediatric range and specify the left eye involvement.

• Avoid using this code if a more specific type of infantile or juvenile cataract is documented (e.g., H26.012 for congenital polar cataract, left eye).
• Ensure laterality is accurately documented and matches the code (left eye).
• If the cataract affects both eyes and is unspecified, consider using the bilateral code (H26.003) or separate codes for each eye if different types are present.
