Acute chest syndrome

This code represents a severe and acute pulmonary complication primarily seen in patients with sickle cell disease. It is characterized by new pulmonary infiltrates on chest X-ray, accompanied by fever, chest pain, tachypnea, wheezing, or cough. It signifies an acute lung injury that can lead to significant morbidity and mortality.

Use this code when documentation clearly indicates a diagnosis of acute chest syndrome, typically in a patient with sickle cell anemia presenting with respiratory distress and new lung infiltrates. Supporting documentation should include physician notes detailing the clinical presentation, imaging findings (e.g., chest X-ray report), and laboratory results.

• Always confirm the diagnosis of acute chest syndrome is explicitly stated by the provider.
• Do not confuse this with other acute respiratory conditions like pneumonia without the specific context of sickle cell disease.
• Code the underlying sickle cell anemia (e.g., 282.6x) as the primary diagnosis when it is the reason for the encounter, and this code as a secondary diagnosis.
