Pauciarticular juvenile rheumatoid arthritis, vertebrae

This code signifies a chronic inflammatory arthropathy affecting the vertebrae in children, characterized by involvement of four or fewer joints during the first six months of the disease. It represents a specific subtype of juvenile idiopathic arthritis with a limited joint distribution.

Apply this code when documentation specifies pauciarticular juvenile rheumatoid arthritis with involvement of the vertebral column. Ensure the patient is under 16 years of age at onset and the condition is chronic.

• Differentiate from other forms of juvenile idiopathic arthritis based on the number of affected joints and specific vertebral involvement.
• Confirm the chronicity of the condition; acute or transient arthropathies would not be coded here.
• Review documentation for laterality or specific vertebral segments if further specificity is available, though this code is for general vertebral involvement.
