ICD-10-CM E11.5: Type 2 diabetes mellitus with circulatory complications

ICD-10-CM code E11.5 represents Type 2 diabetes mellitus with circulatory complications. It is an active diagnosis concept nested under the parent category E11. Chronic hyperglycemia in diabetes can cause damaging macrovascular and microvascular complications, increasing cardiovascular risks. 1 2

Plain-language overview

Code E11.5 identifies a diagnosis of Type 2 diabetes mellitus accompanied by circulatory complications, classifying this specific health status as a Disease or Syndrome. 1

What this code represents

The E11.5 diagnosis code is a child concept of E11, which is the broader category for Type 2 diabetes mellitus within the Endocrine, nutritional and metabolic diseases chapter. 1 5

Within the E11 category, E11.5 is one of several specific complication codes, distinct from E11.9 which denotes Type 2 diabetes mellitus without complications. 5

Clinical context

Persistent hyperglycemia in diabetes can cause damaging macrovascular complications, leading to a two-fold to four-fold increased risk of cardiovascular diseases for affected patients. 2

People with diabetes face a higher risk for heart disease, and smoking doubles the risk of heart disease in individuals diagnosed with diabetes compared to those who do not smoke. 4

Documentation considerations

The official terminology record for E11.5 indicates that the concept is active and has no narrower child concepts within the ICD-10-CM hierarchy as of the 2026 version. 1

Coverage and utilization context

Health care providers screen for diabetes and related complications, such as cardiovascular disease, and refer patients to self-management education and support services to help prevent or delay health problems. 3

What the sources add

While terminology records define E11.5 as an active diagnosis code, clinical sources explain that diabetes complications often share risk factors and one complication can worsen others. 1 4

Clinical guidance emphasizes care coordination among interprofessional team members to improve outcomes for patients affected by Type 2 diabetes mellitus and its associated complications. 2
