Code Description

ICD-10 D56.5 is a billable code used to indicate a diagnosis of hemoglobin e-beta thalassemia.

Key Diagnostic Point:

Hemoglobin E-beta thalassemia is a genetic blood disorder characterized by the production of abnormal hemoglobin, specifically Hemoglobin E, in conjunction with beta thalassemia. This condition arises from mutations in the HBB gene, which encodes the beta-globin subunit of hemoglobin. Patients with Hemoglobin E-beta thalassemia typically exhibit varying degrees of anemia, which can range from mild to severe, depending on the specific genetic mutations inherited. The condition is prevalent in Southeast Asian populations and can lead to symptoms such as fatigue, pallor, and splenomegaly due to increased hemolysis and ineffective erythropoiesis. Laboratory findings often reveal microcytic hypochromic anemia, elevated levels of Hemoglobin E, and abnormal red blood cell morphology. Management may include regular monitoring, blood transfusions, and iron chelation therapy to prevent iron overload. 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 genetic inheritance patterns.
  • Differentiation from other hemoglobinopathies and thalassemias.
  • Need for precise documentation of laboratory findings.
  • Potential for co-morbid conditions affecting coding.

Audit Risk Factors

  • Inadequate documentation of genetic testing results.
  • Failure to specify the severity of anemia.
  • Misclassification with other types of thalassemia.
  • Lack of comprehensive patient history.
