Congenital hydrocephalus, unspecified

This code signifies the presence of an abnormal accumulation of cerebrospinal fluid (CSF) within the ventricles of the brain, present at birth, without further specification of its cause or type. This condition leads to increased intracranial pressure and can result in developmental delays and neurological deficits if left untreated.

This code is appropriate when documentation confirms congenital hydrocephalus but lacks details regarding its etiology (e.g., communicating, non-communicating, obstructive). It should be used when the provider has not specified the type of hydrocephalus or when the specific type is unknown at the time of coding.

• Avoid using this code if the documentation specifies the type of congenital hydrocephalus (e.g., communicating, obstructive); instead, use a more specific code from the Q03 series.
• Always review the entire medical record for additional details that might allow for more precise coding.
• Consider querying the provider if the documentation is ambiguous or if a more specific type of hydrocephalus is suspected but not explicitly stated.
