Combined forms of age-related cataract, left eye

This code signifies the presence of multiple types of age-related cataracts affecting the left eye. It indicates that the patient presents with a combination of senile cataract forms, such as cortical, nuclear, and/or posterior subcapsular, rather than a single isolated type. This condition leads to progressive opacification of the lens, impairing vision.

Apply this code when documentation specifies "combined forms" or "mixed types" of age-related cataract in the left eye. This is appropriate when the ophthalmologist identifies more than one morphological type of senile cataract during examination, such as both nuclear sclerosis and cortical opacities. The medical record should clearly indicate the laterality and the mixed presentation.

• Do not use this code if only one specific type of age-related cataract (e.g., nuclear, cortical) is documented for the left eye; use the more specific code.
• Ensure the documentation explicitly states "combined forms" or lists multiple types of senile cataracts for the left eye to support this code.
• If both eyes are affected by combined forms, use the appropriate bilateral code or separate codes for each eye if the types differ.
