Rheu arthrit w rheu factor of l shoulder w/o org/sys involv

This code signifies seropositive rheumatoid arthritis affecting the left shoulder, without any systemic complications or involvement of other organ systems. It indicates a chronic inflammatory autoimmune disease primarily impacting the synovial joints, confirmed by the presence of rheumatoid factor.

Use this code when documentation clearly states a diagnosis of rheumatoid arthritis with positive rheumatoid factor, specifically localized to the left shoulder. This applies when there are no documented manifestations of the disease in other organs (e.g., lungs, heart, kidneys, vasculitis).

• Ensure documentation explicitly states "left shoulder" and "rheumatoid factor positive."
• Do not use if there is any mention of systemic involvement or complications; instead, select a more specific code from the M05.7 category.
• Confirm the absence of organ or systems involvement; if present, a different subcategory (M05.1-M05.6) would be appropriate.
