Charcot's joint, unspecified wrist

This code describes a neuropathic arthropathy affecting the wrist, specifically Charcot's joint, where the underlying neurological condition is not specified or known. It involves progressive joint destruction due to loss of proprioception and pain sensation, leading to repetitive microtrauma and subsequent degeneration.

Use this code when documentation clearly indicates Charcot's arthropathy of the wrist, but the specific underlying neurological cause (e.g., diabetes, syphilis, syringomyelia) is not identified or documented. This diagnosis is typically supported by imaging studies showing joint disorganization, bone resorption, and fragmentation, alongside clinical signs of neuropathy.

• Always attempt to identify and code the underlying neurological condition causing the Charcot's joint, if known, as a primary or additional diagnosis.
• If the laterality of the wrist is specified (right or left), use the more specific codes M14.631 or M14.632, respectively.
• Differentiate from other forms of arthropathy; Charcot's joint is distinct due to its neuropathic origin.
