Sickle-cell thalassemia without crisis

This code identifies a chronic, inherited blood disorder characterized by the co-occurrence of sickle cell trait and thalassemia, but without an acute exacerbation or "crisis" event. Patients typically exhibit mild to moderate anemia due to the abnormal hemoglobin structure and reduced hemoglobin production.

Assign this code for patients diagnosed with sickle-cell thalassemia who are not experiencing an acute painful crisis, acute chest syndrome, or other acute complications at the time of encounter. Documentation should clearly state the diagnosis of sickle-cell thalassemia and explicitly indicate the absence of a crisis.

• Do not use this code if the patient is experiencing an acute sickle cell crisis; instead, select a more specific code from the D57.0-D57.2 series.
• Ensure documentation differentiates between sickle cell trait, thalassemia trait, and the combined sickle-cell thalassemia.
• Code any associated manifestations or complications, such as splenomegaly or chronic leg ulcers, in addition to this code.
