ICD-10 Code E11.43 – Type 2 diabetes mellitus with diabetic autonomic (poly)neuropathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.43 – Type 2 diabetes mellitus with diabetic autonomic (poly)neuropathy
What it is
This code identifies type 2 diabetes complicated by diabetic autonomic neuropathy, sometimes with broader polyneuropathy involvement. It reflects nerve damage affecting involuntary body functions in a patient with diabetes.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include autonomic nerve dysfunction such as gastrointestinal, bladder, cardiovascular, or sweating abnormalities, along with diabetic neuropathy evidence.
When to use this code
Use E11.43 when the provider documents type 2 diabetes and specifically links it to diabetic autonomic neuropathy. It may also apply when autonomic neuropathy is described as diabetic polyneuropathy in the chart. Do not infer the link without clear documentation.
Do not use for
Do not use this code for type 2 diabetes without documented autonomic neuropathy. Also avoid it when neuropathy is due to another cause or the record only says “neuropathy” without a diabetic attribution.
Coding tip
Confirm the provider explicitly connects the neuropathy to diabetes before assigning E11.43.
