K71.1Toxic liver disease with hepatic necrosis

K71.1 is the ICD-10-CM diagnosis code for toxic liver disease with hepatic necrosis. It belongs to category K71 (toxic liver disease), 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 K71 (toxic liver disease), K71.1 is specifically for toxic liver disease with hepatic necrosis. Related codes cover with cholestasis (K71.0), with acute hepatitis (K71.2), with chronic persistent hepatitis (K71.3), with chronic lobular hepatitis (K71.4), with chronic active hepatitis (K71.5), with hepatitis, not elsewhere classified (K71.6), with fibrosis and cirrhosis of liver (K71.7), with other disorders of liver (K71.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: K71.10 (without coma) and K71.11 (with coma).

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.
