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

This code signifies a diagnosis of seropositive rheumatoid arthritis affecting the left wrist. It indicates the presence of rheumatoid factor (RF) in the patient's blood, and that the disease is localized to the wrist joint without evidence of systemic complications or involvement of other organs.

This code is appropriate when documentation confirms a diagnosis of rheumatoid arthritis, specifically impacting the left wrist, and laboratory results indicate a positive rheumatoid factor. It should be used when there is no mention of extra-articular manifestations or organ system involvement due to the rheumatoid arthritis.

• Ensure documentation explicitly states "left wrist" and "rheumatoid factor positive" to support this specific code.
• Differentiate from seronegative rheumatoid arthritis (M06.0-) or other inflammatory arthropathies.
• If there is any documented organ involvement (e.g., lung, heart), a more specific code from the M05.1-M05.7 subcategories with organ involvement would be required.
