Type 1 diabetes mellitus with diabetic amyotrophy

This code signifies Type 1 diabetes mellitus complicated by diabetic amyotrophy, a rare form of diabetic neuropathy characterized by severe, asymmetric muscle weakness and wasting, typically affecting the proximal muscles of the lower extremities. It results from nerve damage due to prolonged hyperglycemia and metabolic dysfunction associated with diabetes.

Apply this code when documentation explicitly states Type 1 diabetes and a diagnosis of diabetic amyotrophy. This diagnosis is often supported by clinical findings of progressive muscle weakness, pain, and atrophy, usually confirmed by electromyography (EMG) and nerve conduction studies.

• Ensure documentation clearly specifies "Type 1" diabetes, not "Type 2" or "unspecified."
• Do not confuse diabetic amyotrophy with other forms of diabetic neuropathy; specific documentation of amyotrophy is required.
• Sequence this code as a primary diagnosis when the amyotrophy is the primary reason for the encounter, or as a secondary diagnosis when managing other diabetic complications.
