Rheumatoid lung disease w rheumatoid arthritis of r shoulder

This diagnosis code signifies a patient presenting with rheumatoid lung disease, a pulmonary manifestation of rheumatoid arthritis (RA), specifically affecting the right shoulder. It indicates systemic RA with both articular involvement of a specific joint and extra-articular involvement of the lungs.

This code is appropriate when documentation clearly states a diagnosis of rheumatoid arthritis with associated lung disease and concurrent involvement of the right shoulder joint. Supporting documentation should include physician notes detailing both the pulmonary findings consistent with rheumatoid lung and the diagnosis of RA affecting the right shoulder.

• Always ensure documentation explicitly links the lung disease to rheumatoid arthritis.
• Verify laterality for the shoulder joint; this code is specific to the right shoulder.
• Consider sequencing this code after the primary rheumatoid arthritis code (e.g., M05.xx) if the lung disease is a manifestation.
