Rheu arthritis of unsp hip w involv of organs and systems

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

Apply this code when documentation confirms a diagnosis of rheumatoid arthritis with hip involvement, and there is explicit mention of extra-articular manifestations affecting other organs (e.g., vasculitis, lung involvement, pericarditis). This code is appropriate when the specific hip (left or right) is not documented.

• Ensure documentation clearly specifies "unspecified hip" if laterality is not provided.
• Confirm the presence of systemic involvement beyond the joints; otherwise, a code from M05.7- series (rheumatoid arthritis with rheumatoid factor of multiple sites without organ or systems involvement) or M06.0- series (seronegative rheumatoid arthritis) may be more appropriate.
• Always sequence the underlying rheumatoid arthritis code first, followed by codes for specific organ manifestations if applicable.
