About K74

K74 is the ICD-10-CM diagnosis code for fibrosis and cirrhosis of liver. It belongs to 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: K74.0 (fibrosis), K74.1 (sclerosis), K74.2 (sclerosis), K74.3 (cirrhosis), K74.4 (cirrhosis), K74.5 (unspecified) and K74.6 (liver).

Don't report K74 together with the conditions in its Excludes1 note: alcoholic cirrhosis (of liver) (K70.3), alcoholic fibrosis of liver (K70.2), cardiac sclerosis of liver (K76.1), cirrhosis (of liver) with toxic liver disease (K71.7) and 2 more.

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