Hydrocephalus ICD-10-CM Codes | 2023

What Hydrocephalus ICD-10 codes can I use?

If you’re looking for Hydrocephalus ICD codes, there are several to pick from. Here are six examples you can use:

• G91.9 - Hydrocephalus, unspecified

This ICD-10 code is meant to be used on a patient confirmed to have Hydrocephalus.

This code has an unspecified label, which means the specific type of Hydrocephalus hasn’t been identified. Once the specific type has been identified, please use a more specific ICD-10 code.

• G91.0 - Communicating hydrocephalus

This ICD-10 code is meant to be used on a patient confirmed to have Communicating Hydrocephalus.

This type of Hydrocephalus is characterized by a blockage that emerges after cerebrospinal fluid leaves the ventricles.

• G91.1 - Obstructive hydrocephalus

This ICD-10 code is meant to be used on a patient confirmed to have Obstructive Hydrocephalus.

Another term for this is Non-communicating Hydrocephalus. It is characterized by cerebrospinal fluid flow being blocked along the narrow passages connecting the ventricles.

• G91.2 - (Idiopathic) normal pressure hydrocephalus

This ICD-10 code is meant to be used on a patient confirmed to have Normal Pressure Hydrocephalus.

The enlarging of ventricles characterizes this due to cerebrospinal fluid build-up, but there’s little to no increase in pressure.

• G91.3 - Post-traumatic hydrocephalus, unspecified

This ICD-10 code is meant to be used on a patient confirmed to have Post-traumatic Hydrocephalus.

This type of Hydrocephalus is also referred to as Hydrocephalus Ex-vacuo. This is characterized by the shrinking of brain tissue around the ventricles due to head injuries or cerebral infarction. Cerebrospinal fluid builds up in the ventricles, which makes them larger. The enlarged ventricles take up the space left by the shrunk brain tissues.

• G91.8 - Other hydrocephalus

This ICD-10 code is meant to be used on a patient confirmed to have a type of Hydrocephalus that doesn’t have a specific ICD-10 code similar to Items 2 to 5.

Are these Hydrocephalus ICD-10 codes billable?

Yes. All these ICD-10 codes for Hydrocephalus are valid and billable.

Clinical information about Hydrocephalus:

Hydrocephalus is a potentially life-threatening medical condition. It’s characterized by the abnormal build-up of cerebrospinal fluid (sometimes referred to as CSF for short) in the brain, specifically in the ventricles.

CSF is an essential part of our bodies because it is responsible for delivering nutrients to our brains and removing waste from them. It also helps with protecting our brains and spinal cords from injuries.

Despite being an essential part of our bodies, an abnormal CSF build-up in the brain isn’t good because it causes the ventricles to enlarge, and the larger they are, the more pressure they exert on our skulls. If left unchecked and untreated, the pressure can cause problems, with brain damage being one of the worst.
