Code Description

ICD-10 Q27.4 is a billable code used to indicate a diagnosis of congenital phlebectasia.

Key Diagnostic Point:

Congenital phlebectasia refers to a localized dilation of a vein that is present at birth. This condition can occur in various veins throughout the body, but it is most commonly observed in the lower extremities. The etiology of congenital phlebectasia is often linked to developmental anomalies in the venous system, leading to abnormal venous wall structure and function. Clinically, patients may present with swelling, discomfort, or cosmetic concerns, particularly if the affected vein is prominent. While congenital phlebectasia is generally considered a benign condition, it can sometimes be associated with other congenital malformations, particularly those affecting the circulatory system, such as congenital heart defects. Accurate diagnosis typically involves imaging studies, such as ultrasound or MRI, to assess the extent of the dilation and to rule out associated vascular anomalies. Management may vary from observation to surgical intervention, depending on the severity of symptoms and the impact on the patient's quality of life.
