Hi,
I have a question that may seem silly but, if a patient has a negative Rheumatoid Factor and a positive Anti- CCP would you use M05.79 Rheumatoid arthritis with rheumatoid factor of multiple sites without organ or systems involvement (Seropositive rheumatoid arthritis) or M05.09 Rheumatoid arthritis without rheumatoid factor, multiple sites (Seronegative rheumatoid arthritis) BY DEFINITION giving a positive result in a test of blood serum. i.e. rheumatoid factor blood test is positive, BUT some of our physicians also count the anti-CCP positive test as seropositive. when coding, should Rheumatoid Factor be the only consideration?
