Rheu lung disease w rheumatoid arthritis of unsp shoulder

This code signifies a systemic autoimmune disorder characterized by chronic inflammation affecting the joints, specifically the shoulder, and concurrently manifesting as lung disease. It indicates the presence of rheumatoid arthritis with pulmonary involvement, where the specific shoulder affected is not documented.

Apply this code when a patient has a confirmed diagnosis of rheumatoid arthritis with associated lung disease, and the medical record specifies shoulder involvement without laterality. Documentation should clearly state both the rheumatoid arthritis and the pulmonary manifestation, along with the affected joint.

• Ensure documentation explicitly links the lung disease to the rheumatoid arthritis.
• Avoid using this code if the laterality of the shoulder involvement is specified; instead, use a more specific code (e.g., M05.121 for right shoulder).
• Always sequence this code as the primary diagnosis if it is the main reason for the encounter, or as a secondary diagnosis if it is a co-morbidity impacting care.
