Juvenile arthritis, unspecified, left wrist

This code signifies an unspecified form of juvenile arthritis affecting the left wrist. It indicates inflammation of the joint in a patient under 16 years of age, where the specific type of juvenile idiopathic arthritis (JIA) has not been determined or documented.

Apply this code when documentation clearly states "juvenile arthritis" or "juvenile idiopathic arthritis" with involvement of the left wrist, but lacks further specificity regarding the JIA subtype (e.g., oligoarticular, polyarticular, systemic). This code is appropriate when the physician has not yet made a definitive diagnosis of a more specific JIA type.

• Do not use this code if a more specific type of juvenile idiopathic arthritis (e.g., M08.032 for enthesitis-related juvenile arthritis, left wrist) is documented.
• Ensure the documentation specifies "left wrist" to support the laterality. If laterality is not specified, an unspecified laterality code should be used.
• Always query the provider for greater specificity regarding the type of juvenile arthritis if possible, to allow for more precise coding.
