Rheu arthritis of l shoulder w involv of organs and systems

This code signifies rheumatoid arthritis affecting the left shoulder, where the autoimmune disease has also manifested in other body systems beyond the joints. This indicates a more severe or systemic presentation of rheumatoid arthritis, requiring comprehensive management.

Apply this code when documentation clearly states rheumatoid arthritis impacting the left shoulder, along with evidence of extra-articular manifestations such as vasculitis, lung involvement, or Felty's syndrome. The physician's notes should explicitly link the systemic involvement to the rheumatoid arthritis diagnosis.

• Ensure the documentation specifies "left shoulder" and not just a general shoulder involvement.
• Verify that the "other organs and systems" involvement is clearly documented and attributed to the rheumatoid arthritis.
• Do not use this code if the systemic involvement is due to a separate, unrelated condition.
