ICD-10 Code E11.59 – Type 2 diabetes mellitus with other circulatory complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.59 – Type 2 diabetes mellitus with other circulatory complications
What it is
This code identifies type 2 diabetes mellitus with a circulatory complication not named elsewhere in the diabetes category. Use it when documentation links diabetes to a vascular or circulation-related problem.
Clinical signs
Clinical features vary; refer to documentation. You may see evidence of diabetes plus a documented circulatory complication, such as peripheral vascular disease or another vascular disorder attributed to diabetes.
When to use this code
Use E11.59 when the provider explicitly documents type 2 diabetes with another circulatory complication and the record supports that relationship. Assign it when the circulatory condition is described as diabetic or diabetes-related. If the chart only says diabetes and a separate vascular problem, check documentation before coding this combination.
Do not use for
Do not use this code for diabetes with kidney, neurologic, or ophthalmic complications. Also avoid it when the circulatory condition is unrelated to diabetes or when documentation does not establish the causal link.
Coding tip
Look for provider wording that connects the vascular condition to diabetes; without that link, code the diabetes and circulatory condition separately.
