Type 1 Excludes
Type 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as G91. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Information
  • (hye-dro-sef-uh-lus) the abnormal buildup of cerebrospinal fluid in the ventricles of the brain.
  • A disorder characterized by an abnormal increase of cerebrospinal fluid in the ventricles of the brain.
  • Excessive accumulation of cerebrospinal fluid within the cranium which may be a congenital or acquired disorder; hydrocephalus ex-vacuo refers to ventricular dilation that occurs as a result of brain substance loss from cerebral infarction and other conditions.
  • Excessive accumulation of cerebrospinal fluid within the cranium which may be associated with dilation of cerebral ventricles, intracranial hypertension; headache; lethargy; urinary incontinence; and ataxia.
  • Excessive gathering of cerebrospinal fluid within the head bone
  • Hydrocephalus is the buildup of too much cerebrospinal fluid in the brain. Normally, this fluid cushions your brain. When you have too much, though, it puts harmful pressure on your brain.there are two kinds of hydrocephalus. Congenital hydrocephalus is present at birth. Causes include genetic problems and problems with how the fetus develops. An unusually large head is the main sign of congenital hydrocephalus. Acquired hydrocephalus can occur at any age. Causes can include head injuries, strokes, infections, tumors and bleeding in the brain. Symptoms of acquired hydrocephalus can include
    • headache
    • vomiting and nausea
    • blurry vision
    • balance problems
    • bladder control problems
    • thinking and memory problems
    hydrocephalus can permanently damage the brain, causing problems with physical and mental development. If untreated, it is usually fatal. With treatment, many people lead normal lives with few limitations. Treatment usually involves surgery to insert a shunt. Medicine and rehabilitation therapy can also help.
  • Hydrocephalus that results from head trauma, brain tumors, intracranial hemorrhage, or meningitis.
  • The abnormal buildup of cerebrospinal fluid in the ventricles of the brain.
