ICD-10 Code E13.51 – Other specified diabetes mellitus with diabetic peripheral angiopathy without gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.51 – Other specified diabetes mellitus with diabetic peripheral angiopathy without gangrene
What it is
This code identifies diabetes mellitus in the “other specified” category with peripheral angiopathy affecting blood vessels in the arms or legs, but without gangrene. Use it when documentation links the vascular complication directly to the diabetes type.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include poor limb circulation, diminished pulses, cool extremities, pain with walking, or other peripheral vascular changes attributed to diabetes.
When to use this code
Use E13.51 when the record states other specified diabetes mellitus and documents peripheral angiopathy as a diabetic complication, with no gangrene present. It fits cases where the provider clearly connects the vascular disorder to diabetes. If the chart does not specify the diabetes type or relationship, check documentation.
Do not use for
Do not use this code if gangrene is documented, because a different code applies. Also avoid it when peripheral vascular disease is present but not documented as diabetic or when the diabetes category is unspecified.
Coding tip
Confirm both elements in the note: the diabetes category and the peripheral angiopathy, then verify that gangrene is explicitly absent.
