ICD-10 Code E11.51 – Type 2 diabetes mellitus with diabetic peripheral angiopathy without gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.51 – Type 2 diabetes mellitus with diabetic peripheral angiopathy without gangrene
What it is
This code identifies type 2 diabetes complicated by peripheral angiopathy, meaning diabetes-related damage to blood vessels in the arms or legs, without gangrene. Use it when the record clearly links the vascular disease to diabetes.
Clinical signs
Clinical features may include poor peripheral circulation, leg pain with walking, cool extremities, diminished pulses, or ischemic skin changes. Clinical features vary; refer to documentation.
When to use this code
Use E11.51 when the provider documents type 2 diabetes with peripheral angiopathy and no gangrene. It is appropriate when the note states diabetic vascular disease affecting the extremities, or when peripheral arterial disease is described as diabetic in origin. Check documentation if causation is unclear.
Do not use for
Do not use this code for diabetes with gangrene, which requires a different code. Also avoid it when peripheral vascular disease is present but not documented as diabetic.
Coding tip
Confirm the record links the peripheral angiopathy to diabetes before assigning E11.51.
