Drug/chem diabetes w diabetic prph angiopath w/o gangrene

This code signifies diabetes mellitus that has developed as a direct result of drug or chemical exposure, specifically presenting with peripheral angiopathy but without the presence of gangrene. Peripheral angiopathy involves disease of the blood vessels outside of the heart and brain, often affecting the legs and feet.

Use this code when documentation clearly links the patient's diabetes to a specific drug or chemical agent, and there is a confirmed diagnosis of diabetic peripheral angiopathy. The medical record must explicitly state the absence of gangrene in the affected peripheral vessels.

• Always identify the specific drug or chemical causing the diabetes, if known, and code it as an adverse effect or poisoning, as appropriate, in addition to this code.
• Ensure documentation differentiates between drug-induced diabetes and other types of diabetes (e.g., Type 1, Type 2) to avoid miscoding.
• Do not use this code if gangrene is present; a different subcategory of E09.5- would be more appropriate.
