About coding liver abscess
The ICD-10-CM code for liver abscess is K75.0 (Abscess of liver). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K75.0.
Within K75 (other inflammatory liver diseases), K75.0 is specifically for abscess of liver. Related codes cover phlebitis of portal vein (K75.1), nonspecific reactive hepatitis (K75.2), granulomatous hepatitis, not elsewhere classified (K75.3), autoimmune hepatitis (K75.4), other specified inflammatory liver diseases (K75.8) and inflammatory liver disease, unspecified (K75.9).
Don't report K75.0 together with the conditions in its Excludes1 note: amebic liver abscess (A06.4), cholangitis without liver abscess (K83.09) and pylephlebitis without liver abscess (K75.1).
The conditions in its Excludes2 note aren't part of K75.0, but may be coded alongside it if the patient has both: acute or subacute hepatitis NOS (B17.9), acute or subacute non-viral hepatitis (K72.0) and chronic hepatitis NEC (K73.8).
