Rheumatoid lung disease w rheumatoid arthritis of unsp elbow

This code signifies the presence of rheumatoid lung disease in a patient also diagnosed with rheumatoid arthritis affecting an unspecified elbow. It describes a systemic manifestation of rheumatoid arthritis where the lungs are involved, alongside articular involvement in the elbow joint.

Apply this code when documentation explicitly states rheumatoid lung disease co-occurring with rheumatoid arthritis of the elbow, without specifying laterality. This typically applies to cases where the provider has not indicated whether the right or left elbow is affected.

• Ensure documentation clearly links the lung disease to the rheumatoid arthritis.
• Avoid using this code if the laterality of the elbow involvement is specified; instead, use the more specific M05.121 or M05.122.
• Sequence this code as a primary diagnosis when the rheumatoid lung disease and elbow arthritis are the focus of the encounter, or as a secondary diagnosis when another condition is primary.
