Juvenile dermatomyositis with respiratory involvement

This code signifies a pediatric autoimmune inflammatory myopathy characterized by muscle weakness and a distinctive skin rash, specifically when the respiratory system is affected. Respiratory involvement can manifest as interstitial lung disease, aspiration pneumonia, or diaphragmatic weakness, significantly impacting the child's breathing and overall health.

Apply this code when documentation confirms a diagnosis of juvenile dermatomyositis and explicitly states the presence of respiratory complications. This includes findings such as abnormal chest imaging, pulmonary function test abnormalities, or clinical signs of respiratory distress directly attributed to the underlying condition.

• Ensure documentation clearly links the respiratory involvement to the juvenile dermatomyositis, rather than an unrelated respiratory illness.
• Code any specific respiratory manifestations (e.g., interstitial lung disease, aspiration pneumonia) as secondary diagnoses.
• Distinguish from adult-onset dermatomyositis; this code is specific to the juvenile form.
