Oth rheumatoid arthritis w rheumatoid factor mult site

This code signifies a diagnosis of rheumatoid arthritis (RA) that is seropositive (rheumatoid factor present) and affects multiple anatomical locations, but does not fit into more specific categories of RA. It indicates a systemic autoimmune disease characterized by chronic inflammation of the joints, leading to pain, swelling, and potential joint damage.

Apply this code when the patient has a confirmed diagnosis of seropositive RA impacting several joints, and the documentation does not specify a more precise type of RA (e.g., with organ involvement, or specific joint involvement like shoulder or hand). Documentation should clearly state "rheumatoid arthritis," "rheumatoid factor positive," and mention involvement of multiple, non-specified sites.

• Ensure the medical record explicitly states "rheumatoid factor positive" to differentiate from seronegative RA (M06.0-).
• Do not use this code if the documentation specifies a particular type of RA with organ involvement (e.g., M05.3- for RA with lung involvement).
• Consider sequencing this code as the primary diagnosis when it is the main reason for the encounter, followed by codes for specific manifestations or complications.
