Rheu arthritis w rheu factor mult site w/o org/sys involv

This code signifies seropositive rheumatoid arthritis affecting multiple joints throughout the body, where there is no evidence of systemic complications or organ damage. It indicates the presence of rheumatoid factor (RF) in a patient diagnosed with RA, but without manifestations like vasculitis, lung disease, or cardiac involvement.

Apply this code when documentation confirms a diagnosis of rheumatoid arthritis, positive rheumatoid factor, and involvement of more than one joint region (e.g., hands and feet, or shoulders and knees) without any specified organ or system involvement. This code is appropriate when the physician explicitly states "without organ involvement" or when no systemic complications are documented.

• Ensure documentation explicitly states "without organ or system involvement" or clearly lacks any mention of systemic manifestations.
• Do not use this code if specific organ involvement (e.g., M05.3- for RA with lung involvement) is documented, even if multiple sites are affected.
• Always sequence this code as the primary diagnosis when it represents the reason for the encounter, followed by codes for specific joint involvement if further detail is required.
