Drug/chem diabetes mellitus w diabetic nephropathy

This code signifies diabetes mellitus that has been caused by a drug or chemical agent, and is further complicated by kidney disease (nephropathy). The nephropathy is a direct consequence of the drug-induced diabetic state.

Apply this code when documentation clearly states that diabetes was induced by a specific drug or chemical, and the patient also presents with diabetic nephropathy. This typically occurs in patients receiving certain medications (e.g., corticosteroids) or exposed to toxins that impair glucose metabolism.

• Always identify the specific drug or chemical causing the diabetes using an additional code from T36-T65.
• Ensure documentation explicitly links the nephropathy to the drug-induced diabetes, not to pre-existing or other forms of diabetes.
• Do not use this code for type 1 or type 2 diabetes with nephropathy; those have their own specific codes.
