Other sickle-cell disorders with acute chest syndrome

This code identifies a patient with a sickle cell disorder, other than sickle cell anemia (Hb SS disease), who is experiencing acute chest syndrome (ACS). ACS is a serious complication characterized by fever, respiratory symptoms (e.g., cough, dyspnea), and a new pulmonary infiltrate on chest X-ray. This diagnosis indicates a specific type of sickle cell disease is present alongside this acute respiratory event.

Apply this code when documentation confirms a diagnosis of a sickle cell disorder other than sickle cell anemia (e.g., sickle cell-hemoglobin C disease, sickle cell-beta thalassemia) and the patient presents with acute chest syndrome. Supporting documentation should include a definitive diagnosis of the underlying sickle cell variant and clinical findings consistent with ACS, such as new lung infiltrates.

• Always sequence the underlying sickle cell disorder first, followed by this code for the acute chest syndrome.
• Distinguish this from D57.01 (sickle-cell anemia with acute chest syndrome) based on the specific type of sickle cell disorder documented.
• Ensure the medical record clearly specifies "acute chest syndrome" and not just general respiratory symptoms.
