ICD-10 Code E10.8 – Type 1 diabetes mellitus with unspecified complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.8 – Type 1 diabetes mellitus with unspecified complications
What it is
E10.8 identifies type 1 diabetes mellitus when the record documents a complication, but the complication is not named. It tells you the patient has insulin-dependent diabetes with an unspecified associated problem.
Clinical signs
Clinical features vary; refer to documentation. The chart should show type 1 diabetes and some complication, but without enough detail to assign a more specific code.
When to use this code
Use E10.8 when the provider clearly links a complication to type 1 diabetes, yet the note does not specify whether it is renal, ophthalmic, neurological, or another defined complication. It is also appropriate when the complication is documented in general terms and no further clarification is available. Check documentation before defaulting to this code.
Do not use for
Do not use E10.8 if the complication is identified more specifically elsewhere in the record. Do not use it for type 2 diabetes, gestational diabetes, or diabetes without a documented complication.
Coding tip
If the complication is vague, query for specificity before assigning E10.8.
