Sickle-cell thalassemia beta zero with acute chest syndrome

This code represents a severe form of sickle cell disease where a patient has inherited both a sickle cell gene and a beta-zero thalassemia gene, leading to a complete absence of beta-globin production. This specific code is used when a patient with this genetic combination experiences acute chest syndrome, a serious complication characterized by fever, chest pain, and pulmonary infiltrates.

Use this code when documentation clearly indicates a diagnosis of sickle-cell beta-zero thalassemia and the patient is concurrently experiencing acute chest syndrome. Supporting documentation should include genetic testing results or a confirmed clinical diagnosis of sickle-cell beta-zero thalassemia, along with clinical findings consistent with acute chest syndrome (e.g., chest X-ray findings, respiratory symptoms).

• Always confirm the specific type of thalassemia (beta zero) and the presence of acute chest syndrome.
• Do not confuse with other sickle-cell thalassemia types (e.g., beta plus) or sickle cell anemia without thalassemia.
• Code additional manifestations or complications of acute chest syndrome (e.g., pneumonia) separately, if documented.
