ICD-10 Code E13.36 – Other specified diabetes mellitus with diabetic cataract (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.36 – Other specified diabetes mellitus with diabetic cataract
What it is
This code identifies diabetes mellitus from another specified cause, when the patient also has a cataract attributed to the diabetes. Use it when the record links the cataract to the diabetic condition.
Clinical signs
Clinical features vary; refer to documentation. Typical cataract findings include lens opacity, blurred vision, glare, or reduced visual acuity, with diabetes noted as the associated condition.
When to use this code
Use E13.36 when the provider documents other specified diabetes mellitus and specifically states diabetic cataract, or clearly connects the cataract to the diabetes. This supports coding of both the diabetes type and the eye complication. Check documentation if the causal link is unclear.
Do not use for
Do not use this code for diabetes without a documented cataract, or for cataracts not linked to diabetes. If the diabetes type is not “other specified,” choose the appropriate diabetic complication code instead.
Coding tip
Confirm that both the diabetes category and the cataract relationship are documented before assigning E13.36.
