Drug/chem diabetes mellitus w oth complication

This code signifies diabetes mellitus that has developed as a direct result of medication use or exposure to a chemical substance, and is accompanied by a specific, but not otherwise classified, complication. This form of diabetes is distinct from Type 1, Type 2, or gestational diabetes, and the complication must be clearly documented.

Apply this code when a patient's diabetes is explicitly attributed to drug or chemical exposure, and the medical record details a specific complication not covered by more granular codes (e.g., neuropathy, nephropathy, retinopathy). Documentation should clearly state the causative drug/chemical and the resulting complication.

• Always sequence the drug/chemical code (T36-T65 with 5th or 6th character of 5) first, followed by this diabetes code.
• Ensure the documentation explicitly links the diabetes and the complication to the drug/chemical etiology.
• Do not use for diabetes caused by therapeutic drug use that is not adverse, or for diabetes secondary to other conditions (e.g., pancreatitis).
