A rheumatology note documents rheumatoid arthritis of multiple sites with rheumatoid factor positive. How should the coder apply specificity?

Short Explanation
RA with 'many joints' and RF-positive is specific gold—use it. Don't hide behind unspecified arthritis or swap in osteoarthritis when the rheumatologist already named rheumatoid disease and the lab status.
Full Explanation
Rheumatoid arthritis codes distinguish site (including multiple sites) and often serostatus (rheumatoid factor positive or negative) when documented. Coders should assign the specificity present in the record rather than unspecified arthritis or an unrelated osteoarthritis code. Active RA under management is not reported as personal history merely because DMARD therapy is prescribed.
