Neurogenic arthritis, not elsewhere classified

This code represents a destructive arthropathy resulting from a neurological disorder that impairs joint sensation and/or proprioception, leading to progressive joint damage. It is characterized by joint instability, effusions, and bone destruction, often without pain due to the underlying neuropathy. This condition is also known as Charcot joint or neuropathic arthropathy.

Use this code when documentation clearly indicates a diagnosis of neurogenic arthritis that is not specified as being due to a particular underlying condition (e.g., diabetes, syphilis). This diagnosis is typically supported by clinical findings of joint degeneration in the presence of a neurological deficit, often confirmed by imaging studies.

• Do not code this with specific causes of neurogenic arthritis like diabetic neuropathic arthropathy (E10-E14 with .610 or .620) or syphilitic neuropathic arthropathy (A52.16).
• Ensure the documentation specifies "not elsewhere classified" or does not identify a more specific underlying cause.
• Sequence this code after the underlying neurological condition if known and documented, unless the neurogenic arthritis is the primary reason for the encounter.
