Oth diabetes w diabetic peripheral angiopathy w/o gangrene

This code signifies a form of diabetes mellitus, not classified as Type 1 or Type 2, that is complicated by peripheral angiopathy. This vascular complication involves narrowing or obstruction of blood vessels in the extremities, specifically without the presence of tissue necrosis or gangrene.

Apply this code when documentation clearly indicates a diagnosis of "other specified diabetes mellitus" (e.g., secondary diabetes due to pancreatectomy or drug-induced) and a co-occurring diabetic peripheral angiopathy. The physician's notes must explicitly state the absence of gangrene.

• Always sequence the diabetes code first, as it is the underlying condition.
• Ensure documentation differentiates "other specified diabetes" from Type 1 (E10.-) or Type 2 (E11.-).
• Verify the absence of gangrene; if present, a different subcategory (E13.52) would be appropriate.
