Juvenile arthritis, unspecified, multiple sites

This code signifies a diagnosis of juvenile arthritis where the specific type of juvenile idiopathic arthritis (JIA) is not documented, and multiple joints are affected. It indicates a chronic inflammatory joint condition occurring in individuals under 16 years of age, without further specification of the JIA subtype.

This code is appropriate when the medical record clearly states a diagnosis of "juvenile arthritis" or "juvenile idiopathic arthritis" affecting multiple sites, but the clinician has not specified a more definitive subtype (e.g., oligoarticular, polyarticular, systemic). It should be used when documentation lacks the detail to assign a more specific JIA code.

• Avoid using this code if the documentation specifies a particular subtype of juvenile idiopathic arthritis (e.g., polyarticular, oligoarticular, systemic onset).
• Ensure the documentation explicitly mentions "multiple sites" or implies widespread joint involvement; otherwise, a code for unspecified site might be more appropriate.
• Query the provider for a more specific diagnosis if possible, as more detailed JIA codes offer better clinical specificity for data analysis and treatment planning.
