Diab due to undrl cond w diab prph angiopath w/o gangrene

This code signifies diabetes mellitus that is a consequence of another underlying disease or condition, rather than type 1 or type 2 diabetes. Specifically, it indicates the presence of diabetic peripheral angiopathy, a microvascular complication affecting blood vessels in the extremities, but without tissue death (gangrene).

Apply this code when documentation clearly states diabetes is secondary to another condition (e.g., cystic fibrosis, pancreatectomy, hemochromatosis) and the patient also exhibits peripheral angiopathy. Ensure the physician explicitly links the angiopathy to the diabetes and confirms the absence of gangrene.

• Always code the underlying condition causing the diabetes first, followed by this code.
• Distinguish carefully from E10.51 (Type 1) or E11.51 (Type 2) with peripheral angiopathy; the key is the "due to underlying condition" etiology.
• If gangrene is present, a different subcategory (E08.52) would be appropriate.
