ICD10 code of Hepatic Encephalopathy and ICD9 code

The primary ICD-10-CM code for Hepatic Encephalopathy is K72.90 (Hepatic failure, unspecified without coma), though specific codes vary based on the presence of coma (K72.91). In the older ICD-9-CM classification system, Hepatic Encephalopathy was most commonly coded as 572.2.

How are medical codes like ICD-10 used for Hepatic Encephalopathy?

Medical coding systems are essential for documenting the clinical burden of Hepatic Encephalopathy. Healthcare providers use these codes to standardize medical records, facilitate insurance billing, and track the prevalence of the condition globally. Because Hepatic Encephalopathy reflects a complex neuropsychiatric syndrome caused by liver dysfunction, precise coding helps clinicians distinguish between acute and chronic presentations.

What are the clinical classifications of Hepatic Encephalopathy?

Clinically, Hepatic Encephalopathy is categorized by the underlying liver disease and the severity of symptoms. The West Haven Criteria is often used alongside coding to grade the severity of Hepatic Encephalopathy, ranging from Grade 0 (minimal) to Grade 4 (coma). Proper diagnosis involves identifying the trigger, such as gastrointestinal bleeding, infection, or electrolyte imbalances.

What diagnostic markers help identify Hepatic Encephalopathy?

While ICD codes provide administrative categorization, diagnosing Hepatic Encephalopathy relies on a combination of clinical evaluation and laboratory testing. Key factors include:

• Elevated blood ammonia levels (though not diagnostic in isolation).


• Assessment of altered mental status, confusion, or personality changes.


• Physical signs such as asterixis (a characteristic "flapping" tremor of the hands).


• Exclusion of other neurological conditions through neuroimaging or lumbar puncture.

Next steps

• Consult a hepatologist or gastroenterologist to establish a long-term management plan for Hepatic Encephalopathy.


• Monitor for early warning signs of cognitive decline, such as sleep-wake cycle disturbances.


• Connect with the 26 members currently sharing their experiences with Hepatic Encephalopathy on DiseaseMaps.org to find peer support.
