ICD-10 Code E13.4 – Other specified diabetes mellitus with neurological complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.4 – Other specified diabetes mellitus with neurological complications
What it is
This code identifies diabetes mellitus from other specified causes when neurological complications are documented. It signals diabetic nerve involvement, but the diabetes type does not fit the more common categories.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include peripheral neuropathy, numbness, tingling, pain, or other nerve dysfunction attributed to diabetes.
When to use this code
Use E13.4 when the provider documents diabetes due to another specified cause and a neurological complication is present. Support may come from notes describing diabetic neuropathy, autonomic neuropathy, or other nerve-related complications linked to that diabetes.
Apply the code only when the neurological complication is clearly associated with the diabetes. If the record does not specify the diabetes category or the complication, check documentation.
Do not use for
Do not use this code for type 1, type 2, or gestational diabetes. It is also not appropriate if the nerve condition is documented without a diabetic link.
Coding tip
Code the diabetes category and the neurological complication only when both are clearly documented together.
