Rheumatoid vasculitis with rheumatoid arthritis of unsp site

This diagnosis code signifies inflammation of blood vessels (vasculitis) that is directly associated with rheumatoid arthritis. It indicates a systemic complication of rheumatoid arthritis where the vasculitis is present but the specific anatomical location of the affected vessels is not documented.

Apply this code when a patient with rheumatoid arthritis is diagnosed with rheumatoid vasculitis, and the medical record does not specify the site of the vasculitis (e.g., cutaneous, visceral, neuropathic). Documentation should clearly link the vasculitis to the underlying rheumatoid arthritis.

• Always sequence the underlying rheumatoid arthritis code first, followed by this code for the vasculitis.
• If the site of the rheumatoid vasculitis is known, use a more specific M05.2- subcategory code (e.g., M05.21 for multiple sites).
• Ensure documentation explicitly states "rheumatoid vasculitis" and its association with rheumatoid arthritis, rather than just "vasculitis" in a patient with RA.
