Drug/chem diabetes w neuro comp w diabetic mononeuropathy

This code signifies diabetes mellitus that has been caused by a drug or chemical, specifically presenting with a single nerve (mononeuropathy) complication due to the diabetic condition. It indicates a direct link between the exogenous substance, the resulting diabetes, and the subsequent neurological damage affecting a specific nerve.

Use this code when documentation clearly states drug or chemical-induced diabetes mellitus and identifies a diabetic mononeuropathy, such as carpal tunnel syndrome or foot drop, as a direct complication. This code is appropriate when the physician explicitly links the diabetes to a specific medication or chemical exposure.

• Ensure documentation specifies "drug or chemical induced" diabetes, not Type 1, Type 2, or gestational.
• Verify the neurological complication is a mononeuropathy and is explicitly attributed to the diabetes.
• Code the specific drug or chemical causing the diabetes as an adverse effect or poisoning, if applicable, in addition to this code.
