Type 2 diabetes mellitus with diabetic amyotrophy

This code signifies type 2 diabetes complicated by diabetic amyotrophy, a rare form of diabetic neuropathy characterized by severe, often asymmetric, muscle weakness and wasting, typically affecting the proximal muscles of the lower extremities. It results from microvascular damage to the nerves supplying these muscles, leading to pain and functional impairment.

Assign this code when documentation explicitly states type 2 diabetes and a diagnosis of diabetic amyotrophy, also known as diabetic lumbosacral plexopathy or Bruns-Garland syndrome. Supporting documentation should include physician notes detailing the characteristic muscle weakness, pain, and neurological findings consistent with this condition in a patient with type 2 diabetes.

• Always sequence the diabetes code first, as it is the underlying etiology.
• Do not confuse diabetic amyotrophy with other forms of diabetic neuropathy, such as polyneuropathy or mononeuropathy, which have distinct codes.
• Ensure the documentation clearly links the amyotrophy to the patient's type 2 diabetes.
