Q03.9
Congenital hydrocephalus, unspecified
Clinical Classification Guidelines
Medical Intelligence & Overview
Congenital hydrocephalus is a condition present at birth that involves an abnormal accumulation of cerebrospinal fluid (CSF) within the brain's ventricles. This results in increased pressure inside the skull, which can cause the head to enlarge and may affect brain development. The term 'unspecified' indicates that the exact type or cause of hydrocephalus has not been classified. Recognizing and managing this condition early is vital for improving outcomes and supporting affected individuals.
