The ICD code Q03 is used to code Hydrocephalus
Hydrocephalus (from Greek hydro-, meaning "water", and kephalos, meaning "head") is a rare medical condition in which there is an abnormal accumulation of cerebrospinal fluid (CSF) in the brain. This causes increased intracranial pressure inside the skull and may cause progressive enlargement of the head if it occurs in childhood, potentially causing convulsion, tunnel vision, and mental disability. It was once informally called "Water on the brain."
|MeSH Codes:||D006849, D006849, D006849, D006849|
|ICD 9 Codes:||331.3, 331.4, 741.0, 742.3|
Hydrocephalus seen on a CT scan of the brain. The black areas in the middle of the brain are abnormally large and filled with fluid.
