Oth rheumatoid arthritis w rheumatoid factor of r shoulder

This code signifies a form of rheumatoid arthritis, an autoimmune disease, where the patient tests positive for rheumatoid factor (RF) and experiences inflammatory arthritis affecting the right shoulder. It indicates a variant of seropositive rheumatoid arthritis that doesn't fit more specific classifications, presenting with symptoms like pain, swelling, and stiffness in the specified joint.

Apply this code when documentation confirms a diagnosis of rheumatoid arthritis with a positive rheumatoid factor, specifically impacting the right shoulder, and the condition is not further specified as with organ or systemic involvement. Supporting documentation should include a positive RF test result and clinical notes detailing the inflammatory arthritis in the right shoulder.

• Ensure documentation explicitly states "right shoulder" and "rheumatoid factor positive."
• Do not use if the rheumatoid arthritis has specific organ or systemic manifestations; refer to more specific M05 codes.
• Confirm that the provider has diagnosed "other" rheumatoid arthritis, not a more defined subtype.
