Rheu arthrit w rheu fctr of right ank/ft w/o org/sys involv

This code identifies seropositive rheumatoid arthritis affecting the right ankle and/or foot, where the rheumatoid factor is present, but there is no systemic involvement of other organs or body systems. It describes a localized manifestation of rheumatoid arthritis.

Use this code when documentation confirms a diagnosis of rheumatoid arthritis with a positive rheumatoid factor, specifically impacting the right ankle and/or foot. Ensure the clinical record explicitly states the absence of extra-articular manifestations or systemic organ involvement.

• Always verify the laterality (right vs. left) and the specific joint(s) affected.
• Confirm the presence of rheumatoid factor (seropositive) as opposed to seronegative rheumatoid arthritis.
• Do not use this code if there is any documented organ or systemic involvement; a more specific code from the M05.7- subcategory would be required.
