Code K76.82

We now have a code (K76.82) for Hepatic Encephalopathy for FY 2023.  This includes documentation such as: “Hepatocerebral intoxication” and “Portal-systemic encephalopathy.” 

It is important to note in the ICD-10-CM manual that we are to Code Also underlying liver diseases 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), icterus of newborn (P55-P59), postprocedural hepatic failure (K91.82), viral hepatitis without hepatic coma (B15.9, B16.1, B16.9, B17.10, B19.10, B19.20, B19.9). 

Patients with hepatic encephalopathy can lose consciousness and go into a hepatic coma.  Therefore, there is an Excludes1 Note that prohibits us from coding hepatic encephalopathy with codes that have ‘with coma’ in the description:  acute and subacute hepatic failure with coma (K72.01), alcoholic hepatic failure with coma (K70.41), chronic hepatic failure with coma (K72.11), hepatic failure with coma (K72.91).
