Type 2 diabetes w diabetic peripheral angiopath w/o gangrene

This code signifies a diagnosis of type 2 diabetes that has led to peripheral angiopathy, a condition where blood vessels in the extremities are narrowed or blocked, but without the presence of tissue death (gangrene). It indicates microvascular or macrovascular complications affecting the limbs due to long-standing diabetes.

This code is appropriate when a patient with type 2 diabetes presents with symptoms or diagnostic findings consistent with peripheral vascular disease, such as claudication, non-healing ulcers (not yet gangrenous), or diminished pulses, and the physician explicitly links these to their diabetes. Documentation should clearly state "diabetic peripheral angiopathy" and confirm the absence of gangrene.

• Always ensure the documentation specifies "type 2 diabetes" and "without gangrene" to accurately assign this code.
• Do not use this code if gangrene is present; a different code from the E11.5 series would be more appropriate.
• Code any associated diabetic foot ulcers or other manifestations of the angiopathy separately, if documented.
