Drug/chem diabetes w diabetic neuropathic arthropathy

This code signifies diabetes mellitus that has been caused by a drug or chemical, and which has led to diabetic neuropathic arthropathy (Charcot joint). This is a severe complication where nerve damage from diabetes results in progressive joint destruction, often in the feet. The underlying cause of the diabetes is explicitly iatrogenic or toxic.

Apply this code when documentation clearly states that diabetes was induced by a specific drug or chemical agent, and the patient presents with Charcot arthropathy directly attributable to this diabetes. Clinical notes should specify the drug/chemical etiology of the diabetes and describe the characteristic joint destruction.

• Always sequence this code first if it is the primary reason for the encounter.
• Ensure documentation explicitly links the diabetes to a drug/chemical and the arthropathy to the diabetes.
• Do not confuse with type 1 or type 2 diabetes with neuropathic arthropathy; the etiology of the diabetes must be drug/chemical induced.
