Unspecified juvenile rheumatoid arthritis, right knee

This code signifies a diagnosis of juvenile rheumatoid arthritis (JRA) where the specific type of JRA is not documented, and the condition primarily affects the right knee. JRA is a chronic inflammatory autoimmune disease affecting children under 16 years of age, characterized by persistent joint inflammation.

This code is appropriate when the provider's documentation confirms a diagnosis of juvenile rheumatoid arthritis impacting the right knee, but does not specify a sub-type (e.g., oligoarticular, polyarticular, systemic). Use this code when the medical record clearly indicates the right knee as the affected joint and lacks further specificity regarding the JRA classification.

• Ensure documentation explicitly states "juvenile rheumatoid arthritis" and specifies the right knee as the affected joint.
• Avoid using this code if a more specific type of juvenile idiopathic arthritis (JIA) is documented (e.g., oligoarticular, polyarticular).
• Always review the entire medical record for any additional details that might allow for a more specific JIA code.
