Rheumatoid lung disease w rheumatoid arthritis of left hip

This code signifies the presence of rheumatoid lung disease in a patient also diagnosed with rheumatoid arthritis specifically affecting the left hip joint. It indicates a systemic manifestation of rheumatoid arthritis impacting both the pulmonary system and a specific large peripheral joint.

Apply this code when documentation clearly states a diagnosis of rheumatoid lung disease co-occurring with rheumatoid arthritis of the left hip. Supporting documentation would include physician notes detailing both conditions, imaging reports confirming lung involvement, and clinical findings related to left hip arthritis.

• Ensure documentation specifies "rheumatoid lung disease" and not just general lung involvement.
• Verify the laterality of the hip involvement is explicitly stated as "left."
• This code inherently links the lung disease to the rheumatoid arthritis; no additional code for rheumatoid arthritis (e.g., M05.9) is typically needed unless further specificity is required for other joints.
