ICD-10 Code E11.40 – Type 2 diabetes mellitus with diabetic neuropathy, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.40 – Type 2 diabetes mellitus with diabetic neuropathy, unspecified
What it is
This code identifies type 2 diabetes mellitus with neuropathy, but the specific nerve complication is not named. Use it when documentation confirms diabetic neuropathy without further detail.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include numbness, tingling, burning pain, or reduced sensation in the feet or hands when the neuropathy is attributed to diabetes.
When to use this code
Use E11.40 when the provider documents diabetic neuropathy or diabetic peripheral neuropathy and does not specify the type. It also fits when the record links neuropathy to type 2 diabetes but gives no further classification. If the note names another diabetic neurologic complication, code that specific condition instead.
Do not use for
Do not use this code for neuropathy without a documented diabetes link. Do not use it when the record specifies a more exact diabetic neurologic complication; check documentation.
Coding tip
Look for the exact provider wording and code the most specific diabetic neuropathy documented.
