(2022) How To Code Encephalopathy ICD 10 – Codes & Guidelines

Encephalopathy ICD 10 coding is made easier with our billing guidelines. This article includes all medical codes you will need to report encephalopathy and related specific codes, such as hepatic encephalopathy and anoxic encephalopathy.

Read on for a summary of the necessary codes followed by a further description.

What Is Encephalopathy?

The term encephalopathy refers to sickness, injury, or dysfunction of the brain. Encephalopathy and brain disease come in a variety of forms. Some are permanent, while others are only transitory.

Some types are present at birth and do not alter, whereas others are acquired later in life and can deteriorate.

Encephalopathy can cause a wide range of symptoms, from minor memory loss or changes in personality complications like dementia, seizures, coma, and death.

The core manifestation of encephalopathy Is altered sensorium, which could accompany physical manifestation such as abnormal limb coordination.

Encephalopathy is often preceded by specific words that explain what is causing the malfunction within the brain.

For example, anoxic encephalopathy Indicates the abnormality within the brain due to oxygen deficit within brain substances. Encephalopathy is not a single disease entity.

Instead, encephalopathy is a collection of illnesses caused by various factors. It’s a severe medical condition that, if left untreated, can result in permanent brain damage.


  • Infectious causes include (bacteria, fungi, viruses, parasites
  • Alcohol toxicity
  • Liver diseases which include liver cirrhosis and liver malignancies
  • Kidney failure

  • Poor nutrition (vitamin B1 deficiency)
  • Drugs induced encephalopathies such as the use of cyclosporine and tacrolimus


The symptoms you experience will vary depending on the type and origin of your encephalopathy.

However, the following are some of the most common:

  • State of confusion
  • Change In personality
  • Loss of memory
  • Inability to focus or think clearly

Diagnosis & Treatment

A complete history is taken, putting medical and drug history Into consideration, investigations such as:

  • Blood and urine tests
  • Cerebrospinal fluid tests
  • Imaging scans can be done which CT scans or MRI
  • An electroencephalography test may be indicated, which help to access electrical activity within the brain

Treatment includes removal of what is causing the encephalopathy after a thorough investigation has been done.

  • Medications such as anti-seizure can be given to abort the seizure
  • Stopping medications that could trigger the disease condition
