Pauciarticular juvenile rheumatoid arthritis, right ank/ft

This code signifies a chronic inflammatory arthritis affecting children, specifically involving four or fewer joints (pauciarticular type), with the right ankle and foot being the affected site. It is a subtype of juvenile idiopathic arthritis (JIA), characterized by persistent joint inflammation.

Apply this code when documentation clearly indicates a diagnosis of pauciarticular juvenile rheumatoid arthritis affecting the patient's right ankle and foot. This diagnosis is typically made by a rheumatologist based on clinical examination, imaging, and laboratory findings.

• Ensure documentation specifies "pauciarticular" and clearly identifies the right ankle and foot as the affected joints.
• Do not confuse with polyarticular JIA (affecting five or more joints) or systemic JIA.
• Consider sequencing this code as a primary diagnosis when it is the main reason for the encounter.
