Hydrocephalus is the buildup of cerebral spinal fluid (CSF) in the brain. CSF levels have the right to rise if there is one imbalance between how much CSF is produced and how much is absorbed into the bloodstream. The excess fluid may increase the dimension of the ventricles and also cause press on the brain, which may damage brain tissue. Hydrocephalus can take place at any kind of age but is more common in infants and older patients.

Common causes of elevated CSF space obstruction that the normal circulation of CSF between ventricles or about other spaces roughly the brain; negative absorption the CSF in blood vessels, probably as result of the inflammation of brain tissues from disease or injury; and overproduction the CSF.

Newborns/Infants Hydrocephalus existing at bear is referred to as congenital hydrocephalus and may result from abnormal advancement of the central nervous system, i m sorry obstructs CSF flow; bleeding in the ventricles the the brain; and inflammation of fetal mind tissue.

Symptoms of hydrocephalus vary based on a patient’s age. Typical signs and also symptoms that hydrocephalus in infants incorporate a bulging or larger-than-expected soft point out on the top of the head, eyes addressed downward, vomiting, sleepiness, irritability, and also seizures.

Congenital hydrocephalus is classified to ICD-9-CM code 742.3. Documentation of chronic hydrocephalus also is indexing to code 742.3. If the hydrocephalus is linked with spina bifida, assign password 741.0. A fifth-digit subclassification will be assigned to determine the region of the spine associated in the spina bifida (eg, cervical, dorsal/thoracic, lumbar).

Older Patients causes of hydrocephalus in older period groups include lesions or tumors the the mind or spinal cord, main nervous system infections, mind hemorrhage native stroke or head injury, and traumatic mind injury.

Symptoms in older kids may include alters in personality, memory, or the ability to reason; bad attention span; changes in facial appearance; untreated eye movements; impaired vision (blurred or twin vision); headache; irritability; negative coordination and balance; extreme sleepiness; and loss that bladder control.

Symptoms in geriatric patients encompass memory loss, gradual loss of other thinking or thinking skills, gait problems, negative coordination and balance, usually slower-than-normal movements, and also loss that bladder control.

Types that Hydrocephalus obtained hydrocephalus might be categorized as communicating or noncommunicating. Communicating hydrocephalus is brought about by a blockage the CSF after ~ it leaves the ventricles. The fluid can quiet flow in between the ventricles. Interacting hydrocephalus is classified to code 331.3 and also includes an additional normal push hydrocephalus.

Noncommunicating hydrocephalus may be documented as obstructive hydrocephalus (331.4) and occurs once the circulation of CSF is blocked along one or more of the small passages connecting the ventricles. One common reason of obstructive hydrocephalus is aqueductal stenosis. The aqueduct that Sylvius is a tiny passage between the 3rd and fourth ventricles. If the narrowing is because of a congenital anomaly, this will be thought about a congenital hydrocephalus (742.3). However, if it is an gained stenosis, climate assign password 331.4. Password 331.4 additionally includes acquired hydrocephalus no otherwise specified.

Documentation of hydrocephalus there is no specification of type will default to code 331.4.

Idiopathic normal pressure hydrocephalus (331.5), additionally documented as normal pressure hydrocephalus, outcomes from excess CSF that affects mind function, yet the fluid pressure commonly is normal. It may result from a subarachnoid hemorrhage, head trauma, infection, or tumor.

Diagnosis and Treatment to diagnose hydrocephalus, the medical professional will perform a thorough history and physical, and also review the signs and also symptoms. A neurological exam may be carry out to evaluate reflexes, muscle strength/tone, balance, coordination, hearing, vision, and sensitivity come touch. In addition, the physician might order mind imaging to evaluate any fluid accumulation.

Hydrocephalus needs to be cure to improve the circulation of CSF and also reduce or prevent mind damage. A versatile tube referred to as a shunt might be put into among the brain ventricles and also tunneled under the skin, with the other finish inserted right into the abdomen or heart. The shunt keeps the CSF relocating in the ideal direction in ~ the proper rate. The patient normally will need the shunt because that his or her whole life.

A shunt placed from the brain to the abdomen or peritoneum is divide to code 02.34, Ventricular shunt to abdominal cavity and also organs, and also sometimes may be recorded as a ventriculoperitoneal shunt. Password 02.34 also includes ventriculocholecystostomy and ventriculoperitoneostomy.

If the shunt is inserted into a different site, assign code 02.22, Intracranial ventricular shunt or anastomosis. Password 02.22 likewise is assigned for ventriculostomy, a procedure the creates a feet at the bottom of the ventricle or in between two ventricles to drain CSF native the brain. A ventriculostomy through an outside ventricular drain is share to password 02.21.

Coding and sequencing for hydrocephalus space dependent ~ above the medical professional documentation in the medical record and also application of the official Coding Guidelines because that inpatient care. Also, use certain AHA Coding Clinic for ICD-9-CM and American clinical Association CPT Assistant references to for sure complete and accurate coding.

Coding for Hydrocephalus in ICD-10-CM In ICD-10-CM, hydrocephalus is classified to group G91, through the following codes depending on the kind of hydrocephalus:

• G91.0, connecting hydrocephalus;

• G91.1, Obstructive hydrocephalus;

• G91.2, (Idiopathic) normal press hydrocephalus;

• G91.3, Posttraumatic hydrocephalus, unspecified;

• G91.4, Hydrocephalus in conditions classified elsewhere;

• G91.8, various other hydrocephalus; and

• G91.9, Hydrocephalus, unspecified.

As displayed above, over there is a code for unspecified hydrocephalus, and also it will not default come obstructive hydrocephalus together it does in ICD-9-CM. In addition, there are two brand-new codes in ICD-10-CM because that posttraumatic hydrocephalus and also hydrocephalus in illness classified elsewhere. If the hydrocephalus outcomes from one more condition, sequence very first the underlying cause, such together neoplasm.

For the procedure coding, a shunt is reported as a bypass in ICD-10-PCS, i beg your pardon is identified as “altering the path of i of the contents of a tubular human body part.” The body component value identifies the beginning of the bypass or shunt, and the qualifier identifies the destination. The password assignment will be broken down as follows:

• personality 1—Section: Ventriculoperitoneal (VP) shunt falls under the Medical and Surgical section of the Procedure Coding System, worth of 0.

• character 2—Body system: The body device for this procedure is the central nervous system, value of 0.

• character 3—Root operation: The root operation for shunt is bypass, value of 1, i beg your pardon is identified as “altering the route of passage of the contents of a tubular human body part.”

• character 4—Body part: The body component for this procedure is typically the cerebral ventricle, which has a character worth of 6.

• personality 5—Approach: A VP shunt procedure can either be done via open method (character worth of 0) or percutaneous approach (character value of 3).

• character 6—Device: The device used is a catheter, i beg your pardon is associated to a one-way valve system. The possible options incorporate autologous tissue substitute (character value of 7), artificial substitute (character value of J), and also nonautologous organization substitute (character value of K). The catheter is commonly a synthetic substitute in this type of procedure.

• personality 7—Qualifier: The qualifier identifies the location of the bypass or shunt. In a VP shunt, the fluid is commonly drained come the peritoneal cavity, worth of 6.
