ICD-10 Code E10.6 – Type 1 diabetes mellitus with other specified complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.6 – Type 1 diabetes mellitus with other specified complications
What it is
This code identifies type 1 diabetes mellitus with a documented complication that is not named in a more specific ICD-10 category. Use it when the record clearly links the complication to type 1 diabetes.
Clinical signs
Clinical features vary; refer to documentation. You may see diabetes-related complications affecting different body systems, but the chart should specify the complication and its connection to type 1 diabetes.
When to use this code
Use E10.6 when the provider documents type 1 diabetes and an associated complication that does not fit a more specific E10 code. This is appropriate when the complication is stated but not otherwise classified. Verify that the note supports a causal relationship between diabetes and the complication.
Do not use for
Do not use this code for type 2 diabetes or for diabetes without a documented complication. If a more specific type 1 diabetes complication code applies, code that instead. Check documentation.
Coding tip
Assign the most specific type 1 diabetes complication code available before defaulting to E10.6.
