ICD-10 Code E11.4 – Type 2 diabetes mellitus with neurological complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.4 – Type 2 diabetes mellitus with neurological complications
What it is
E11.4 identifies type 2 diabetes mellitus when neurological complications are documented. Use it when diabetes is linked to nerve involvement rather than uncomplicated diabetes.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include diabetic neuropathy, numbness, tingling, burning pain, or reduced sensation in the extremities.
When to use this code
Use E11.4 when the provider states type 2 diabetes with a neurological complication and does not specify a more detailed subcode. It also applies when the record links diabetes to neuropathy or another nerve disorder. Code any documented manifestation separately when required.
Do not use for
Do not use this code for type 1 diabetes, gestational diabetes, or uncomplicated type 2 diabetes. Check documentation if the neurologic condition is present but not clearly attributed to diabetes.
Coding tip
Verify the provider’s wording and code the documented neurologic complication to the highest available specificity.
