Rheumatoid vasculitis w rheumatoid arthritis of unsp wrist

This code signifies a systemic inflammatory condition characterized by vasculitis occurring in a patient with rheumatoid arthritis, specifically affecting an unspecified wrist. Rheumatoid vasculitis is a severe extra-articular manifestation of rheumatoid arthritis, involving inflammation of blood vessels.

Use this code when documentation clearly indicates rheumatoid vasculitis as a complication of rheumatoid arthritis, with the affected joint specified as the wrist but without laterality (left or right) being documented. Supporting documentation should include physician notes detailing the diagnosis of rheumatoid arthritis and the presence of vasculitis, with specific mention of wrist involvement.

• Ensure the documentation specifies "rheumatoid vasculitis" and not just general vasculitis in a patient with RA.
• Only use this code when laterality of the affected wrist is not specified in the medical record. If laterality is known, a more specific code (M05.231 or M05.232) should be used.
• Always sequence the underlying rheumatoid arthritis code (M05.-) first, followed by this code for the manifestation.
