ICD-10 Code E10.59 – Type 1 diabetes mellitus with other circulatory complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.59 – Type 1 diabetes mellitus with other circulatory complications
What it is
This code identifies type 1 diabetes mellitus when the chart documents a circulatory complication that is not named in a more specific diabetes category. Use it when the vascular problem is linked to diabetes and no better code is available.
Clinical signs
Clinical features vary; refer to documentation. You may see evidence of peripheral or other circulatory disease, but the record should clearly connect the complication to type 1 diabetes.
When to use this code
Use E10.59 when the provider documents type 1 diabetes with a circulatory complication and does not specify a more precise diabetic complication code. It may apply when the note describes diabetic vascular disease, peripheral circulatory disorder, or another circulatory issue attributed to diabetes. Check documentation for the exact complication.
Do not use for
Do not use this code for type 2 diabetes, gestational diabetes, or circulatory disorders that are not documented as diabetic complications. If the record identifies a more specific diabetic circulatory code, use that instead.
Coding tip
Assign the diabetes code only when the provider explicitly links the circulatory complication to type 1 diabetes.
