Charcot's joint, right wrist

This code signifies neurogenic arthropathy affecting the right wrist. Charcot's joint, or neuropathic osteoarthropathy, is a progressive degenerative arthropathy resulting from impaired pain sensation and proprioception, leading to repetitive microtrauma and joint destruction. In this specific instance, the right wrist is the affected anatomical site.

Apply this code when documentation clearly indicates a diagnosis of Charcot's joint specifically affecting the right wrist. This typically occurs in patients with underlying neurological conditions such as diabetes, syphilis, or syringomyelia, which compromise nerve function to the joint. Supporting documentation should include clinical findings consistent with neuropathic joint destruction and laterality.

• Ensure the documentation specifies "Charcot's joint" or "neuropathic osteoarthropathy" and clearly identifies the right wrist as the affected joint.
• Do not confuse with general osteoarthritis (M19.-) or other specific arthropathies unless the neurogenic etiology is explicitly stated.
• Always code the underlying neurological condition (e.g., E10.40 for Type 1 diabetes with neurological complications) first, as Charcot's joint is a manifestation of that primary disease.
