ICD-10 Code E11.36 – Type 2 diabetes mellitus with diabetic cataract (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.36 – Type 2 diabetes mellitus with diabetic cataract
What it is
E11.36 identifies type 2 diabetes mellitus with cataract attributed to the diabetes. Use this code when the record links the cataract to the diabetic condition.
Clinical signs
Clinical features vary; refer to documentation. Cataracts commonly present with blurred vision, glare, and reduced visual clarity, and the chart should support a diabetic association.
When to use this code
Use E11.36 when the provider documents type 2 diabetes with diabetic cataract, or clearly states the cataract is due to diabetes. It may apply in ophthalmology, primary care, or consult notes when the causal relationship is recorded. Check documentation if the cataract is present but not linked to diabetes.
Do not use for
Do not use this code for cataracts without a documented diabetic cause, or for other diabetes complications. If the record does not connect the cataract to diabetes, code the cataract and diabetes separately as supported.
Coding tip
Verify that the provider explicitly links the cataract to type 2 diabetes before assigning E11.36.
