About K75.0

K75.0 is the ICD-10-CM diagnosis code for abscess of liver. It belongs to category K75 (other inflammatory liver diseases), block K70-K77 (diseases of liver) and chapter 11 (diseases of the digestive system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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).

As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 441 (Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis with MCC, relative weight 1.8219), DRG 442 (Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis with CC, relative weight 0.9602), DRG 443 (Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis without CC/MCC, relative weight 0.6885), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 07 (Diseases and Disorders of the Hepatobiliary System and Pancreas) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

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

Before ICD-10, this condition was coded in ICD-9-CM as 572.0 (abscess of liver).
