Rheumatoid lung disease w rheumatoid arthritis of unsp hip

This code signifies a systemic autoimmune disorder characterized by both rheumatoid arthritis affecting an unspecified hip joint and associated lung involvement. The lung disease is a direct manifestation of the rheumatoid arthritis, indicating extra-articular involvement.

Apply this code when documentation confirms a diagnosis of rheumatoid arthritis with specific mention of lung disease and involvement of the hip, without further specification of laterality. This code is appropriate when the medical record clearly links the lung pathology to the underlying rheumatoid arthritis.

• Always sequence the underlying rheumatoid arthritis code first, followed by codes for specific manifestations like lung disease.
• Ensure documentation specifies "rheumatoid lung disease" rather than other types of lung disease to justify this code.
• If laterality of the hip is specified (e.g., right or left), a more specific code should be used.
