Rheu arthrit w rheu factor of r shoulder w/o org/sys involv

This code signifies seropositive rheumatoid arthritis affecting the right shoulder joint, without any systemic complications or involvement of other organs. It indicates the presence of rheumatoid factor (RF) in the patient's blood, confirming the autoimmune nature of the arthritis.

Apply this code when documentation specifies a diagnosis of rheumatoid arthritis, positive rheumatoid factor, and involvement localized to the right shoulder. Ensure the medical record explicitly states the absence of any extra-articular manifestations or organ system involvement.

• Confirm the laterality (right shoulder) is clearly documented.
• Verify that "without organ or systems involvement" is explicitly stated or clearly implied by the absence of documentation of such involvement.
• Do not use this code if the rheumatoid factor status is unknown or negative; refer to codes for seronegative rheumatoid arthritis.
