Sickle-cell thalassemia beta plus without crisis

This code identifies a specific type of inherited blood disorder where an individual has both sickle cell trait and beta thalassemia trait, resulting in a milder form of sickle cell disease. In this "beta plus" variant, some normal beta-globin production occurs, leading to less severe symptoms compared to other sickle cell thalassemia types. This particular code specifies that the patient is not currently experiencing an acute sickle cell crisis.

Use this code for patients diagnosed with sickle-cell beta plus thalassemia who are stable and not in an acute vaso-occlusive or other sickle cell crisis. Documentation should clearly state the diagnosis of "sickle-cell beta plus thalassemia" or "sickle-cell thalassemia beta plus" and explicitly confirm the absence of a crisis. This code is appropriate for routine follow-up, management of chronic symptoms, or when the condition is noted incidentally.

• Ensure documentation specifies "beta plus" to differentiate from other sickle-cell thalassemia types (e.g., beta zero).
• Always verify the absence of an acute crisis; if a crisis is present, a different code from the D57.0-D57.2 series would be appropriate.
• Do not confuse with sickle cell trait (D57.3) or other forms of thalassemia without the sickle cell component.
