About the condition

Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.

Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a form of arthritis that causes pain, swelling, and stiffness in your joints. RA is an autoimmune disease. Although it is most common in the wrist and fingers, this disease can cause your immune system to attack any joint tissue. The inflammation (swelling) that comes with RA can also affect other body parts. Inflammation could cause medical issues in your eyes, skin, heart, nerves, blood, or lungs.
