K72 (Hepatic failure, not elsewhere classified) compared with R40.2423 (Glasgow coma scale score 9-12, at hospital admission), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. R40.2423 carries an Excludes1 note covering K72: “somnolence, stupor and coma in hepatic failure (K72.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
