K71Toxic liver disease

K71 is the ICD-10-CM diagnosis code for toxic liver disease. 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 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: K71.0 (with cholestasis), K71.1 (with hepatic necrosis), K71.2 (with acute hepatitis), K71.3 (with chronic persistent hepatitis), K71.4 (with chronic lobular hepatitis), K71.5 (with chronic active hepatitis), K71.6 (with hepatitis, not elsewhere classified), K71.7 (with fibrosis and cirrhosis of liver) and 2 more.

The conditions in its Excludes2 note aren't part of K71, but may be coded alongside it if the patient has both: alcoholic liver disease (K70.-) and Budd-Chiari syndrome (I82.0).

Code first: poisoning due to drug or toxin, if applicable (T36-T65 with fifth or sixth character 1-4).

Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).

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