Other juvenile arthritis, right knee

This code signifies a diagnosis of juvenile arthritis affecting the right knee, where the specific type of juvenile arthritis is not otherwise classified (e.g., not juvenile rheumatoid arthritis, juvenile psoriatic arthritis, etc.). It indicates chronic inflammation of the right knee joint in a patient under 16 years of age, without further specification of the underlying arthritic condition.

Use this code when documentation clearly states "juvenile arthritis" or "juvenile idiopathic arthritis" affecting the right knee, and no more specific type of juvenile arthritis is identified. This code is appropriate when the provider has ruled out or not yet definitively diagnosed a more specific form of juvenile arthritis.

• Ensure the documentation specifies "right knee" and "juvenile arthritis" or "juvenile idiopathic arthritis."
• Do not use if a more specific type of juvenile arthritis (e.g., polyarticular, oligoarticular, systemic) is documented; instead, use the appropriate specific code from the M08.0-M08.4 series.
• Always sequence this code after any underlying systemic condition if applicable and documented.
