K72.0Acute and subacute hepatic failure

K72.0 is the ICD-10-CM diagnosis code for acute and subacute hepatic failure. It belongs to category K72 (hepatic failure, not elsewhere classified), block K70-K77 (diseases of liver) and chapter 11 (diseases of the digestive system). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within K72 (hepatic failure, not elsewhere classified), K72.0 is specifically for acute and subacute hepatic failure. Related codes cover chronic hepatic failure (K72.1) and hepatic failure, unspecified (K72.9).

To report this condition, pick the subcode that matches the documentation: K72.00 (without coma) and K72.01 (with coma).

Use an additional code, if applicable, for ascites (R18.8).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
