ICD-10 Code E11.5 – Type 2 Diabetes Mellitus with Circulatory Complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.5 – Type 2 diabetes mellitus with circulatory complications
What it is
This code identifies type 2 diabetes mellitus when circulatory complications are documented. Use it when diabetes is linked to vascular disease or impaired blood flow, not when diabetes is uncomplicated.
Clinical signs
Clinical features vary; refer to documentation. You may see evidence of peripheral vascular disease, poor limb perfusion, ischemic changes, or other circulatory problems attributed to diabetes.
When to use this code
Use this code when the provider clearly documents type 2 diabetes with a circulatory complication. It may apply when the record states diabetic vascular disease, peripheral circulatory disorder, or similar wording. If the complication is not specified, check documentation before coding.
Do not use for
Do not use this code for uncomplicated type 2 diabetes or for circulatory disease that is not linked to diabetes. If the record only says “diabetes” without a vascular complication, choose a more specific code after review.
Coding tip
Always code the diabetes first, then verify the circulatory complication is explicitly documented and diabetes-related.
