ICD-10 Code E08.6 – Diabetes mellitus due to underlying condition with other specified complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E08.6 – Diabetes mellitus due to underlying condition with other specified complications
What it is
This code identifies diabetes that results from another underlying condition and includes a specified complication not captured by a more specific E08 code. Use it when the record links the diabetes to the causative condition and names the complication.
Clinical signs
Clinical features vary; refer to documentation. You should expect evidence of diabetes plus a documented complication, such as a named organ or system effect, in the setting of an underlying disease causing the diabetes.
When to use this code
Use E08.6 when the provider documents diabetes secondary to another condition and describes a complication that is not separately indexed to a more specific code. The underlying condition should also be coded, when instructed by ICD-10-CM guidelines. Check documentation if the complication is unspecified or if another E08 subcode fits better.
Do not use for
Do not use this code for primary diabetes mellitus, for diabetes without a documented underlying cause, or when a more specific complication code is available. Do not assign it if the record does not clearly link the diabetes to the underlying condition.
Coding tip
Verify both the cause of diabetes and the exact complication before coding, and sequence the underlying condition as directed by the record and guideline.
