Oth rheumatoid arthritis with rheumatoid factor of left hand

This code signifies a form of rheumatoid arthritis affecting the left hand, characterized by the presence of rheumatoid factor, but not meeting the criteria for other more specific types of seropositive rheumatoid arthritis. It indicates an inflammatory autoimmune condition primarily impacting the synovial joints of the left hand.

Apply this code when documentation specifies rheumatoid arthritis of the left hand, explicitly states the presence of rheumatoid factor, and does not provide further specificity (e.g., without organ or system involvement, or with specific organ involvement). This code is appropriate when the provider has diagnosed "other" seropositive RA of the left hand.

• Ensure documentation clearly specifies "left hand" and "rheumatoid factor positive."
• Do not use if a more specific code for seropositive rheumatoid arthritis (e.g., with specific organ involvement) is applicable.
• Consider sequencing this code after any codes for associated systemic manifestations, if present and documented.
