M05.159

Rheumatoid lung disease with rheumatoid arthritis of unspecified hip

Clinical Classification Guidelines

Medical Intelligence & Overview

Rheumatoid lung disease is a complication associated with rheumatoid arthritis (RA), a chronic autoimmune disorder that primarily affects the joints. When RA affects the lungs, it can lead to inflammation and damage to lung tissue, which can impair breathing and overall lung function. The specific code M05.159 refers to cases where someone has rheumatoid lung disease along with RA affecting an unspecified hip. This dual condition can present challenges and requires careful management to address both joint and lung health effectively.
