Drug/chem diabetes w neurological comp w diabetic polyneurop

This code signifies diabetes mellitus that has been caused by a drug or chemical, specifically presenting with damage to multiple peripheral nerves. The polyneuropathy is a direct neurological complication stemming from the drug-induced diabetic state.

Apply this code when documentation clearly states diabetes mellitus is drug or chemical-induced and the patient is experiencing diabetic polyneuropathy as a complication. This typically occurs in patients on medications known to affect glucose metabolism or following exposure to certain chemicals.

• Always identify the specific drug or chemical causing the diabetes, if known, and code it as an adverse effect or poisoning.
• Ensure the documentation explicitly links the polyneuropathy to the drug-induced diabetes.
• Do not use this code for type 1 or type 2 diabetes with polyneuropathy; those have distinct codes.
