ICD-10 Code E08.59 – Diabetes mellitus due to underlying condition with other circulatory complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E08.59 – Diabetes mellitus due to underlying condition with other circulatory complications
What it is
This code identifies diabetes caused by another underlying condition, with a documented circulatory complication not named elsewhere in the diabetes category. Use it when the diabetes and vascular problem are both clearly linked in the record.
Clinical signs
Clinical features vary; refer to documentation. You may see signs of diabetes plus circulatory disease, such as vascular insufficiency or other blood-vessel complications, when the provider states the complication is related to the underlying-condition diabetes.
When to use this code
Use E08.59 when the chart documents diabetes due to another condition and a circulatory complication that does not fit a more specific diabetes code. Make sure the underlying cause is identified and the complication is described as associated with the diabetes.
Code the additional condition when documentation supports it, and do not assume the relationship without provider wording. If the circulatory issue is specified elsewhere in the record, follow the more precise code guidance.
Do not use for
Do not use this code for primary diabetes without an underlying cause, or when the circulatory complication is not documented. Check documentation if the record names a more specific diabetic vascular complication.
Coding tip
Verify both the underlying condition and the circulatory complication are documented before assigning E08.59.
