Charcot's joint, left shoulder

This code represents Charcot's arthropathy affecting the left shoulder joint. This is a progressive degenerative arthropathy resulting from loss of proprioception and pain sensation, leading to repetitive microtrauma and joint destruction. It is often associated with underlying neurological conditions such as syringomyelia or diabetic neuropathy.

Use this code when documentation explicitly states Charcot's joint affecting the left shoulder. This diagnosis is typically supported by imaging findings (e.g., X-rays showing joint disorganization, fragmentation, and osteolysis) and a history of a predisposing neurological condition.

• Ensure laterality is clearly documented as "left shoulder" to support this specific code.
• Always code the underlying neurological condition causing the Charcot's arthropathy first, as it is the etiology.
• Do not confuse with other forms of degenerative arthritis or osteonecrosis; Charcot's joint has a distinct pathophysiology.
