Monoarthritis, not elsewhere classified, right wrist

This code signifies inflammation affecting a single joint, specifically the right wrist, that is not attributable to a more specific underlying condition such as gout, infection, or rheumatoid arthritis. It represents an isolated inflammatory process within the right wrist joint.

Apply this code when documentation clearly indicates monoarthritis of the right wrist without a definitive etiology that would allow for a more specific diagnosis code. This is appropriate when the physician has ruled out or not yet identified a systemic or infectious cause for the single joint inflammation.

• Ensure documentation specifies "right wrist" and confirms monoarticular involvement.
• Avoid using this code if a more specific diagnosis for the monoarthritis (e.g., infectious, crystal-induced, psoriatic) is documented.
• Consider sequencing this code after any underlying systemic conditions if they are present and contributing to the monoarthritis, but the monoarthritis itself is not classified elsewhere.
