Unspecified juvenile rheumatoid arthritis, left shoulder

This code signifies an inflammatory arthropathy affecting the left shoulder joint in a patient under 16 years of age, where the specific subtype of juvenile idiopathic arthritis (JIA) has not been determined. It indicates chronic synovitis and joint pain without further specification of systemic involvement or other characteristic features of JIA subtypes.

Apply this code when documentation clearly states "juvenile rheumatoid arthritis" or "juvenile idiopathic arthritis" affecting the left shoulder, but lacks details to classify it into a more specific JIA subtype (e.g., oligoarticular, polyarticular, systemic onset). This code is appropriate for initial diagnoses when further workup is pending or when the specific subtype remains undiagnosed.

• Avoid using this code if documentation specifies a particular JIA subtype (e.g., M08.052 for polyarticular JIA, left shoulder).
• Ensure the patient's age at onset or diagnosis is consistent with juvenile arthritis (typically under 16 years).
• Always query for more specific details regarding the JIA subtype if available in the medical record.
