Oth diabetes mellitus with diabetic neuropathic arthropathy

This code signifies a form of diabetes mellitus, not otherwise classified as type 1 or type 2, that has led to diabetic neuropathic arthropathy. This arthropathy, also known as Charcot joint, is a progressive degenerative joint disease resulting from nerve damage due to diabetes, often affecting the feet and ankles.

Apply this code when documentation clearly indicates a diagnosis of "other specified diabetes mellitus" and a co-occurring diabetic neuropathic arthropathy. This typically involves patients with long-standing diabetes experiencing joint destruction, deformity, and instability, particularly in the lower extremities, confirmed by imaging and clinical examination.

• Always code the underlying diabetes first, followed by this code to specify the complication.
• Ensure documentation explicitly states "other specified diabetes mellitus" and "neuropathic arthropathy" or "Charcot joint" linked to diabetes.
• Do not use for neuropathic arthropathy due to causes other than diabetes.
