Other juvenile arthritis, multiple sites

This code signifies a diagnosis of juvenile arthritis that does not fit into other specific categories of juvenile idiopathic arthritis (JIA) and affects multiple joints throughout the body. It represents a chronic inflammatory condition presenting before the age of 16, characterized by persistent joint swelling, pain, and stiffness in various anatomical locations.

Apply this code when documentation specifies a diagnosis of "other" or "unspecified" juvenile arthritis affecting more than one joint, and more specific JIA subtypes (e.g., oligoarticular, polyarticular, systemic) have been ruled out or are not documented. Supporting documentation should clearly indicate the multi-site involvement and the diagnosis of juvenile arthritis.

• Ensure the medical record explicitly states "multiple sites" or lists several affected joints.
• Do not use this code if a more specific type of juvenile idiopathic arthritis (e.g., M08.0-, M08.2-) is documented.
• Always review the entire medical record for any additional specific diagnoses that might supersede this more general code.
