Rheu arthritis of r shoulder w involv of organs and systems

This diagnosis code signifies a systemic autoimmune disorder affecting the right shoulder joint, where the inflammatory process of rheumatoid arthritis has extended beyond the joints to impact other bodily systems. This indicates a more severe or advanced stage of the disease with extra-articular manifestations.

Apply this code when documentation clearly states a diagnosis of rheumatoid arthritis affecting the right shoulder, and there is explicit mention of involvement of other organs or systems (e.g., vasculitis, lung involvement, Felty's syndrome). This code is appropriate when the physician has identified and documented these systemic complications in addition to the joint involvement.

• Ensure documentation specifies "right shoulder" and clearly identifies systemic involvement beyond the joint.
• Do not use this code if only joint involvement is noted; a different M05 subcategory without systemic involvement would be more appropriate.
• Sequence this code as the primary diagnosis when the rheumatoid arthritis with systemic involvement is the reason for the encounter, or as a secondary diagnosis if another condition is the primary focus but this condition is actively managed.
