Drug/chem diabetes w diabetic chronic kidney disease

This code identifies diabetes mellitus that has been caused by a drug or chemical, specifically when the patient also has diabetic chronic kidney disease. It signifies a direct causal link between medication/chemical exposure and the onset of diabetes, complicated by renal impairment.

Use this code when documentation clearly states drug- or chemical-induced diabetes and explicitly mentions the presence of diabetic chronic kidney disease. This is appropriate for patients whose diabetes developed as an adverse effect of therapeutic drug use or exposure to toxic chemicals, and who are now experiencing kidney complications due to this specific type of diabetes.

• Always sequence the drug or chemical as an external cause code (T36-T65) after the diabetes code.
• Ensure documentation specifies "drug-induced" or "chemical-induced" diabetes; do not assume based on medication lists alone.
• Requires additional codes to specify the type of chronic kidney disease (e.g., N18.x for stage of CKD).
