Clinical notes

Code also

Two codes may be needed to fully describe a condition, but unlike Code First/Use Additional Code, the sequencing order is not mandated by convention.

  • 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)
  • 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)

Excludes1 (not coded here)

An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).

  • 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)
