Charcot's joint, left wrist

This code represents Charcot's arthropathy affecting the left wrist. This is a progressive degenerative arthropathy resulting from loss of proprioception and pain sensation, often secondary to an underlying neurological condition like diabetes or syphilis, leading to joint destruction.

Use this code when documentation specifies neurogenic arthropathy, or Charcot's joint, localized to the patient's left wrist. This diagnosis is typically supported by clinical findings of joint instability, swelling, and deformity, often in the context of a pre-existing neuropathy.

• Always confirm the specific joint involved and laterality (left, right, bilateral) from the physician's documentation.
• Code the underlying neurological condition (e.g., diabetes mellitus with neurological complications) first, as Charcot's joint is a manifestation of that primary disease.
• Distinguish from other forms of degenerative arthritis; Charcot's joint has a distinct neuropathic etiology.
