Obstructive hydrocephalus
ICD-10 G91.1 is a billable code used to indicate a diagnosis of obstructive hydrocephalus.
Obstructive hydrocephalus is a condition characterized by an accumulation of cerebrospinal fluid (CSF) within the ventricles of the brain due to a blockage in the normal flow of CSF. This obstruction can occur at various points along the CSF pathway, such as the aqueduct of Sylvius or the foramina of Monro. The increased pressure from the accumulated fluid can lead to a range of neurological symptoms, including headaches, nausea, vomiting, cognitive dysfunction, and visual disturbances. In infants, signs may include an enlarged head circumference, irritability, and developmental delays. The condition can be caused by congenital malformations, tumors, infections, or traumatic injuries. Diagnosis typically involves neuroimaging techniques such as MRI or CT scans to visualize the ventricles and identify the site of obstruction. Treatment often requires surgical intervention, such as the placement of a shunt to divert CSF and relieve pressure on the brain. Long-term management may involve monitoring for complications and addressing any underlying causes of the obstruction.
Detailed neurological examination findings, imaging results, and treatment plans.
Patients presenting with headaches, cognitive changes, or developmental delays in children.
Ensure all imaging studies are documented and correlate with clinical findings.
Surgical notes, post-operative care plans, and follow-up assessments.
Patients undergoing shunt placement or other surgical interventions for hydrocephalus.
Document the indication for surgery and any complications that arise.
Used for patients diagnosed with obstructive hydrocephalus requiring surgical intervention.
Surgical notes detailing the procedure and indication for shunt placement.
Neurosurgeons must document the specific type of shunt and any complications.
Common causes include congenital malformations, tumors, infections, and traumatic injuries that block the flow of cerebrospinal fluid.
Diagnosis is typically made through neuroimaging techniques such as MRI or CT scans, which reveal ventricular enlargement and the site of obstruction.
