Clinical Information
Hepatic Encephalopathy
a syndrome characterized by central nervous system dysfunction in association with liver failure, including portal-systemic shunts. clinical features include lethargy and confusion (frequently progressing to coma); asterixis; nystagmus, pathologic; brisk oculovestibular reflexes; decorticate and decerebrate posturing; muscle spasticity; and bilateral extensor plantar reflexes (see reflex, babinski). electroencephalography may demonstrate triphasic waves.

Tabular List of Diseases and Injuries
The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.
Inclusion Terms
Inclusion TermsThese terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Hepatic encephalopathy, NOS
- Hepatic encephalopathy without coma
- Hepatocerebral intoxication
- Portal-systemic encephalopathy
Code Also
Code AlsoA "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
- underlying liver disease, such as:
- acute and subacute hepatic failure without coma K72.00
- alcoholic hepatic failure without coma K70.40
- chronic hepatic failure without coma K72.10
- hepatic failure with toxic liver disease without coma K71.10
- hepatic failure without coma K72.90

- viral hepatitis without hepatic coma B15.9 B16.1 B16.9 B17.10 B19.10 B19.20 B19.9
Type 1 Excludes
Type 1 ExcludesA type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
