What This Code Means

Type 2 diabetes that has caused clouding of the eye lens (cataract), leading to blurred or dimmed vision.

Coding Tips

• •Diabetic cataracts may develop earlier and progress faster than age-related cataracts
• •Document whether the cataract is unilateral or bilateral for complete clinical documentation

Clinical Significance

Type 2 diabetes mellitus with diabetic cataract reflects lens opacity caused by osmotic and metabolic changes from chronic hyperglycemia. Diabetic cataracts develop earlier and progress more rapidly than age-related cataracts, with the osmotic stress from sorbitol accumulation in the lens being a key pathogenic mechanism. These cataracts can significantly impair vision and may complicate diabetic retinopathy monitoring by obscuring fundoscopic examination.

Documentation Requirements

• ✓The provider must document cataract formation as a complication of Type 2 diabetes, distinguishing it from age-related or other causes of cataract.
• ✓Ophthalmological examination findings including cataract type (posterior subcapsular is most common in diabetes), visual acuity impact, and surgical planning should be recorded.
• ✓Laterality should be specified.
