Code Description

ICD-10 Q89.01 is a billable code used to indicate a diagnosis of asplenia (congenital).

Key Diagnostic Point:

Asplenia, or the congenital absence of the spleen, is a rare condition that can occur as an isolated anomaly or as part of a syndrome involving multiple congenital malformations. The spleen plays a crucial role in the immune system, particularly in filtering blood and fighting infections. Children with congenital asplenia are at increased risk for infections, particularly from encapsulated bacteria such as Streptococcus pneumoniae and Haemophilus influenzae. Clinical management often includes prophylactic antibiotics and vaccinations to mitigate infection risk. Asplenia can be associated with other congenital malformations, including cardiac defects, gastrointestinal anomalies, and other organ system abnormalities. Diagnosis is typically made through imaging studies, such as ultrasound or MRI, which can visualize the absence of the spleen. Genetic counseling may be indicated, especially if asplenia is part of a syndrome. Understanding the implications of asplenia is essential for pediatric care, as these patients require careful monitoring and preventive measures to ensure their health and well-being.

Frequently Asked Questions

What are the implications of congenital asplenia for patient care?

Patients with congenital asplenia require careful monitoring for infections, vaccination against encapsulated organisms, and possibly prophylactic antibiotics. Regular follow-up with pediatricians and specialists is essential to manage their health effectively.
