Arthropathy associated with neurological disorders

This code describes joint disease (arthropathy) that develops as a secondary complication of an underlying neurological condition. This can include conditions where nerve damage affects joint sensation, muscle control, or trophic support, leading to joint degeneration, instability, or deformity.

Use this code when documentation clearly links a patient's arthropathy to a diagnosed neurological disorder, such as Charcot joint (neurogenic arthropathy) due to diabetes, syringomyelia, or spinal cord injury. The medical record should specify the neurological etiology impacting the joint.

• Always code the underlying neurological disorder first, followed by this code for the arthropathy.
• Distinguish from primary osteoarthritis or other inflammatory arthropathies not directly caused by a neurological deficit.
• Ensure documentation specifies the affected joint(s) and the causal neurological condition.
