ICD Code G91.9

ICD code G91.9 is hydrocephalus, unspecified, which refers to an abnormal buildup of fluid in the brain without further specification of the type or cause.

1. Presence of abnormal accumulation of cerebrospinal fluid (CSF) within the ventricles of the brain

2. Clinical symptoms of increased intracranial pressure, such as headache, nausea, vomiting, or altered mental status

3. Evidence of ventriculomegaly on neuroimaging (CT or MRI)

4. Absence of a clearly identified underlying cause or type of hydrocephalus after diagnostic evaluation

5. Signs of gait disturbance, urinary incontinence, or cognitive impairment that may be associated with hydrocephalus

6. No documentation specifying whether the hydrocephalus is communicating, non-communicating, congenital, or acquired

Relevant CPT codes that may be used to treat ICD code G91.9 include:

- 62223: Creation of shunt, ventriculoatrial, ventriculoperitoneal, ventriculopleural; with or without reservoir

- 62230: Injection, procedure for ventriculography, cisternography, or shuntogram

- 62258: Removal of ventricular shunt

- 62256: Replacement of ventricular shunt

- 61107: Twist drill, burr hole(s), or trephine with aspiration of ventricular cyst or hematoma

- 61070: Puncture of lateral or third ventricle for aspiration, injection, or drainage

These CPT codes are commonly associated with the management and treatment of ICD code G91.9.
