Drug/chem diabetes w neuro comp w oth diabetic neuro comp

This code signifies diabetes mellitus that has been caused by a drug or chemical agent, and is further complicated by a neurological condition other than diabetic neuropathy, such retinopathy or nephropathy. It indicates a direct link between the exogenous substance and the onset of diabetes, along with a specific neurological sequela.

This code is appropriate when documentation clearly states drug-induced diabetes and identifies a neurological complication, such as diabetic amyotrophy, mononeuropathy, or polyneuropathy, that is not specified elsewhere. Supporting documentation should include a definitive diagnosis of drug-induced diabetes and a detailed description of the neurological manifestation.

• Always sequence the drug or chemical as an external cause code (T36-T65) after the diabetes code.
• Ensure the documentation specifies "drug-induced" or "chemical-induced" diabetes, not just diabetes in a patient taking medication.
• Distinguish from E08.49 (diabetes mellitus due to underlying condition with other diabetic neurological complication) and E10-E13 codes for type 1, type 2, or other specified diabetes with neurological complications.
