Rheumatoid vasculitis w rheumatoid arthritis of unsp elbow

This diagnosis code signifies a severe systemic manifestation of rheumatoid arthritis (RA) characterized by inflammation of blood vessels (vasculitis) occurring in a patient with RA. Specifically, it indicates that the elbow joint is affected by the underlying rheumatoid arthritis, but the laterality (right or left) is not specified.

Use this code when documentation clearly states a diagnosis of rheumatoid vasculitis in a patient with rheumatoid arthritis, and the elbow is identified as an affected joint. The physician's notes should explicitly link the vasculitis to the RA and mention elbow involvement without specifying right or left.

• Ensure documentation explicitly links the vasculitis to rheumatoid arthritis; otherwise, a separate vasculitis code may be more appropriate.
• If laterality of the elbow is specified (right or left), a more specific code within the M05.22 subcategory should be used.
• Always sequence the underlying rheumatoid arthritis code (e.g., M05.xx) as the primary diagnosis if the vasculitis is a manifestation.
