Rheu arthritis w rheu factor of l elbow w/o org/sys involv

This code signifies a diagnosis of rheumatoid arthritis affecting the left elbow joint, where the rheumatoid factor (RF) is present in the patient's blood. Importantly, this specific diagnosis indicates that there is no systemic involvement of other organs or body systems due to the rheumatoid arthritis.

Use this code when documentation confirms rheumatoid arthritis with a positive rheumatoid factor test, specifically localized to the left elbow. This code is appropriate when the medical record explicitly states the absence of extra-articular manifestations or organ system involvement.

• Ensure documentation clearly specifies "left elbow" and "without organ or systems involvement."
• Confirm a positive rheumatoid factor test result is documented to support the "with rheumatoid factor" specificity.
• Differentiate from other rheumatoid arthritis codes that specify different anatomical sites or include systemic involvement.
