Drug/chem diabetes mellitus w unsp complications

This code signifies diabetes mellitus that has developed as a direct result of exposure to a drug or chemical agent, where the specific complications arising from this diabetes are not documented or are unknown. It represents an iatrogenic or toxicological origin of diabetes, distinct from Type 1, Type 2, or gestational diabetes.

Apply this code when documentation clearly states drug-induced or chemical-induced diabetes, and no specific complications (e.g., nephropathy, retinopathy, neuropathy) are mentioned. This is appropriate for initial diagnoses or when the patient's diabetes is being managed without identified complications.

• Always sequence this code before any codes for specific complications if they are later identified.
• Do not use this code for diabetes due to underlying conditions like pancreatitis or cystic fibrosis; those have specific ICD-10-CM codes.
• Ensure the medical record explicitly links the diabetes to a drug or chemical exposure.
