ICD-10 Code E13.5 – Other specified diabetes mellitus with circulatory complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.5 – Other specified diabetes mellitus with circulatory complications
What it is
This code identifies diabetes mellitus due to another specified cause with circulatory complications. Use it when the record links the diabetes to vascular disease affecting blood flow.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include peripheral vascular disease, poor circulation, ischemic symptoms, or other documented circulatory impairment associated with diabetes.
When to use this code
Use E13.5 when the provider documents diabetes from another specified cause and also documents a circulatory complication. The complication must be clearly linked to the diabetes in the record. If the chart does not specify the diabetes type or the vascular issue, check documentation before coding.
Do not use for
Do not use this code for type 1, type 2, or gestational diabetes. It is also wrong if the circulatory problem is documented without a diabetes-related link.
Coding tip
Confirm both the diabetes etiology and the circulatory complication in the provider note before assigning E13.5.
