Sickle-cell thalassemia, unsp, with splenic sequestration

This code signifies a form of sickle cell disease where an individual has inherited both a sickle cell gene and a beta-thalassemia gene, resulting in an unspecified type of sickle-cell thalassemia. The "with splenic sequestration" component indicates an acute, life-threatening complication characterized by rapid enlargement of the spleen due to pooling of red blood cells. This condition can lead to severe anemia and hypovolemic shock.

Use this code for patients diagnosed with sickle-cell thalassemia (unspecified type) who are experiencing an acute episode of splenic sequestration. Documentation must clearly state the diagnosis of sickle-cell thalassemia and explicitly mention the presence of splenic sequestration, often evidenced by a sudden drop in hemoglobin and an enlarged, tender spleen.

• Ensure documentation specifies "unspecified" sickle-cell thalassemia; otherwise, a more specific code (e.g., D57.21x) may be appropriate.
• This code inherently includes the splenic sequestration complication; no additional code for the sequestration itself is needed.
• Always review the medical record for any underlying causes or other complications that may require additional coding.
