ICD-10 Code E10.49 – Type 1 diabetes mellitus with other diabetic neurological complication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.49 – Type 1 diabetes mellitus with other diabetic neurological complication
What it is
This code identifies type 1 diabetes with a neurological complication not named by a more specific diabetic neuropathy code. Use it when documentation links the nerve problem directly to diabetes.
Clinical signs
Clinical features vary; refer to documentation. You may see neuropathic pain, numbness, tingling, weakness, or autonomic nerve involvement when the record supports a diabetic cause.
When to use this code
Use E10.49 when the provider documents type 1 diabetes and a diabetic neurological complication, but the complication is not described by a more specific code. It may apply to neuropathy or other nerve disorders attributed to diabetes. Code the diabetes first and confirm the relationship in the note.
Do not use for
Do not use this code for type 2 diabetes, unspecified diabetes, or neurological disorders without a documented diabetic link. If the chart names a more specific diabetic neuropathy code, use that instead.
Coding tip
Look for explicit wording such as “diabetic neuropathy” or another diabetes-related nerve complication before assigning E10.49.
