Oth rheumatoid arthritis w rheumatoid factor of right wrist

This code signifies a diagnosis of rheumatoid arthritis, confirmed by the presence of rheumatoid factor, affecting the right wrist. It specifies a form of rheumatoid arthritis that doesn't fit into more specific categories like rheumatoid arthritis with organ involvement or rheumatoid arthritis with polyarticular involvement.

This code is appropriate when documentation clearly indicates a diagnosis of rheumatoid arthritis, positive rheumatoid factor, and involvement of the right wrist, without further specification of systemic complications or widespread joint involvement. Supporting documentation would include physician notes detailing the diagnosis, serological test results for rheumatoid factor, and physical examination findings localized to the right wrist.

• Ensure documentation explicitly states "right wrist" and "rheumatoid factor positive."
• Differentiate from codes for seronegative rheumatoid arthritis or rheumatoid arthritis affecting other joints.
• Consider sequencing with codes for any associated systemic manifestations if present, but not specified by this "other" category.
