ICD-10 Code E11.6 – Type 2 diabetes mellitus with other specified complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.6 – Type 2 diabetes mellitus with other specified complications
What it is
This code identifies type 2 diabetes mellitus when the record documents a complication that is specified but not named by a more exact E11 subcategory. Use it when the diabetes-related problem is clear, but no more specific code fits.
Clinical signs
Clinical features vary; refer to documentation. You may see diabetes with a clearly described complication, such as a secondary condition linked to the diabetes, without enough detail to assign a more specific code.
When to use this code
Use E11.6 when the provider documents type 2 diabetes and an additional complication, but the chart does not support a more specific E11 code. It is appropriate when the complication is explicitly tied to diabetes and no other code captures it better. Check documentation if the complication is vague or incomplete.
Do not use for
Do not use this code for uncomplicated type 2 diabetes or when a more specific complication code is available. If the record does not clearly link the condition to diabetes, check documentation and code the documented diagnosis instead.
Coding tip
Always code the complication as specifically as the documentation allows, and query the provider when the diabetes-related condition is unclear.
