Drug/chem diabetes mellitus w oth skin complications

This code signifies diabetes mellitus that has been caused by a drug or chemical agent, specifically when the patient also presents with skin complications other than foot ulcer. These skin complications can include various dermatological manifestations directly attributable to the drug-induced diabetes.

Apply this code when documentation clearly states a diagnosis of diabetes mellitus resulting from medication or chemical exposure, alongside a documented skin condition (e.g., necrobiosis lipoidica diabeticorum, diabetic dermopathy, bullosis diabeticorum) that is not a foot ulcer. Ensure the causal link between the drug/chemical and the diabetes, and the diabetes and the skin complication, is explicitly stated.

• Always identify the specific drug or chemical causing the diabetes using an external cause code (T36-T65) in conjunction with this code.
• Do not use this code for diabetes due to underlying genetic defects, pancreatic disease, or other specified causes; those have separate codes.
• Distinguish "other skin complications" from diabetic foot ulcers (E09.621) and other specific diabetic complications.
