ICD-10 Code E13.39 – Other specified diabetes mellitus with other diabetic ophthalmic complication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.39 – Other specified diabetes mellitus with other diabetic ophthalmic complication
What it is
This code identifies diabetes mellitus due to another specified cause, with an eye complication not classified elsewhere. Use it when the record names a diabetic ophthalmic problem linked to other specified diabetes.
Clinical signs
Findings may include diabetic eye disease such as retinopathy, macular edema, cataract, glaucoma, or other documented ophthalmic involvement. Clinical features vary; refer to documentation.
When to use this code
Use E13.39 when the provider documents other specified diabetes mellitus and a related ophthalmic complication, but the eye condition is not captured by a more specific code. It is appropriate when the chart clearly links the eye disorder to diabetes. Check documentation if the diabetic cause or eye diagnosis is unclear.
Do not use for
Do not use this code for type 1 or type 2 diabetes, or for eye conditions not documented as diabetic complications. Do not use it when a more specific ophthalmic diabetes code is available.
Coding tip
Verify both the diabetes type and the exact eye complication before assigning E13.39.
