Code Description

ICD-10 D57.418 is a billable code used to indicate a diagnosis of sickle-cell thalassemia, unspecified, with crisis with other specified complication.

Key Diagnostic Point:

Sickle-cell thalassemia is a genetic blood disorder characterized by the presence of both sickle cell disease and thalassemia, leading to abnormal hemoglobin production. Patients with this condition experience episodes of pain known as sickle cell crises, which occur when sickle-shaped red blood cells obstruct blood flow in small vessels. The unspecified nature of this code indicates that the specific type of thalassemia is not detailed, which can complicate treatment and management. Complications may include hemolytic anemia, where red blood cells are destroyed faster than they can be produced, leading to fatigue, pallor, and jaundice. Other complications can arise from organ damage due to chronic hypoxia and vaso-occlusive events. Genetic factors play a crucial role, as both sickle cell disease and thalassemia are inherited conditions, necessitating thorough family history documentation. Management often involves pain control, hydration, and blood transfusions, and may require coordination with hematology specialists for comprehensive care.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Variability in clinical presentation and severity of symptoms
  • Need for precise documentation of complications
  • Differentiation between types of thalassemia and sickle cell disease
  • Potential for multiple co-existing conditions

Audit Risk Factors

  • Inadequate documentation of crisis events
  • Failure to specify complications
  • Misclassification of thalassemia type
  • Lack of genetic testing documentation

Frequently Asked Questions

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

Sickle-cell thalassemia is a combination of sickle cell disease and thalassemia, leading to unique clinical presentations and management challenges, whereas sickle cell disease primarily refers to the presence of sickle-shaped red blood cells without the thalassemia component.
