ICD-10 Code E10.4 – Type 1 diabetes mellitus with neurological complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.4 – Type 1 diabetes mellitus with neurological complications
What it is
This code identifies type 1 diabetes with nerve-related complications. Use it when diabetes is documented with diabetic neuropathy or other neurological involvement.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include numbness, tingling, burning pain, reduced sensation, or other neuropathic deficits linked to diabetes.
When to use this code
Use E10.4 when the provider documents type 1 diabetes and a neurological complication, such as diabetic neuropathy. It is appropriate when the nerve disorder is described as diabetic or due to diabetes. Check documentation if the neurological manifestation is unspecified.
Do not use for
Do not use this code for type 2 diabetes or for diabetes without a documented neurological complication. If the nerve condition is unrelated to diabetes, code the neurological disorder instead.
Coding tip
Confirm that the record links the neurological finding to type 1 diabetes before assigning E10.4.
