ICD-10 Code E10.51 – Type 1 diabetes mellitus with diabetic peripheral angiopathy without gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.51 – Type 1 diabetes mellitus with diabetic peripheral angiopathy without gangrene
What it is
This code identifies type 1 diabetes complicated by peripheral angiopathy, meaning diabetes-related disease affecting blood vessels in the limbs. There is no gangrene documented.
Clinical signs
Clinical features may include poor peripheral circulation, diminished pulses, limb pain, or ischemic skin changes. Clinical features vary; refer to documentation.
When to use this code
Use E10.51 when the record clearly documents type 1 diabetes and diabetic peripheral angiopathy without gangrene. Apply it when vascular complications are attributed to diabetes, such as peripheral arterial disease or limb ischemia, and gangrene is not present. Check documentation if the vascular diagnosis is not explicitly linked to diabetes.
Do not use for
Do not use this code if gangrene is documented, because a different diabetes code applies. Do not assign it for peripheral vascular disease without a stated diabetic relationship; check documentation.
Coding tip
Confirm both the type 1 diabetes diagnosis and the absence of gangrene before coding.
