Code Description

ICD-10 B74 is a used to indicate a diagnosis of filariasis.

Key Diagnostic Point:

Filariasis, classified under ICD-10 code B74, refers to a group of diseases caused by parasitic worms known as filariae. These parasites are transmitted to humans through the bites of infected mosquitoes and can lead to various clinical manifestations, including lymphatic filariasis, which is characterized by severe swelling and deformities, particularly in the limbs and genitals. The condition can also cause tropical pulmonary eosinophilia and other systemic effects. Understanding the clinical significance of filariasis is crucial, as it can lead to long-term disability and impact the quality of life of affected individuals. Early diagnosis and treatment are essential to prevent complications and manage symptoms effectively.

ICD-10 Improvements

The clinical impact of filariasis extends beyond individual patient outcomes, as it poses significant public health challenges in endemic regions. Effective management of filariasis can improve population health by reducing the burden of disease and associated disabilities. Additionally, healthcare providers must be aware of the trends in filariasis prevalence and the importance of preventive measures, such as vector control and community education, to mitigate the impact of this disease on healthcare systems.
