Cortical age-related cataract, unspecified eye

This code signifies a type of age-related cataract characterized by opacities primarily affecting the outer layer (cortex) of the lens. It indicates that the specific eye affected (right or left) was not documented or is unknown. This condition leads to progressive blurring of vision due to the clouding of the lens.

Use this code when the medical record explicitly states a diagnosis of cortical age-related cataract, but does not specify laterality. Documentation should clearly indicate the cataract's cortical location and its association with aging. This code is appropriate when the physician's notes lack information regarding which eye is affected.

• Do not use this code if laterality (right or left eye) is documented; instead, choose the more specific H25.011 or H25.012.
• Ensure the documentation specifies "cortical" to differentiate from other types of age-related cataracts (e.g., nuclear, posterior subcapsular).
• Consider sequencing this code as a primary diagnosis if it is the main reason for the encounter, or as a secondary diagnosis if it is a co-morbidity.
