Rheu arthrit of unsp shoulder w involv of organs and systems

This code signifies rheumatoid arthritis affecting an unspecified shoulder joint, accompanied by systemic manifestations impacting other organs or bodily systems. This indicates a more severe or widespread form of rheumatoid arthritis beyond just the joint involvement.

Apply this code when documentation confirms rheumatoid arthritis affecting the shoulder, and there is explicit mention of involvement of other organs (e.g., lungs, heart, kidneys, eyes) or systemic complications. This is appropriate when the specific shoulder (left or right) is not documented.

• Ensure documentation clearly specifies "unspecified shoulder" and details the "other organs and systems" involved.
• Do not use this code if only joint involvement is present; instead, select a code from M05.0-M05.5 or M06.0-M06.9.
• If the specific shoulder is known, use a more precise code from M05.611 (right) or M05.612 (left).
