Code Description

ICD-10 D57.4 is a billable code used to indicate a diagnosis of sickle-cell thalassemia.

Key Diagnostic Point:

Sickle-cell thalassemia is a genetic blood disorder that combines features of both sickle cell disease and thalassemia. It occurs when an individual inherits one sickle cell gene (HbS) from one parent and a thalassemia gene from the other. This condition leads to the production of abnormal hemoglobin, which can cause red blood cells to become rigid and sickle-shaped, leading to hemolytic anemia. Patients may experience episodes of pain due to vaso-occlusive crises, increased risk of infections, and complications related to chronic hemolysis. The severity of symptoms can vary widely depending on the specific type of thalassemia inherited (alpha or beta) and the proportion of sickle hemoglobin present. Management typically involves regular monitoring, pain management, and preventive measures against infections. Blood transfusions and hydroxyurea may be utilized to reduce complications and improve quality of life. Genetic counseling is also recommended for affected individuals and their families to understand inheritance patterns and reproductive options.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of both sickle cell disease and thalassemia genetics.
  • Differentiation from other hemolytic anemias can be challenging.
  • Documentation must specify the type of thalassemia involved.
  • Clinical management may involve multiple specialties, complicating coding.

Audit Risk Factors

  • Inadequate documentation of genetic testing results.
  • Failure to specify the type of thalassemia.
  • Misclassification of sickle cell disease severity.
  • Omission of co-existing conditions.

Frequently Asked Questions

What is the difference between sickle-cell thalassemia and sickle cell disease?

Sickle-cell thalassemia is a specific type of sickle cell disease that occurs when a person inherits both a sickle cell gene and a thalassemia gene. This results in a unique set of symptoms and complications that differ from those seen in individuals with sickle cell disease alone.
