ICD-10 code for liver mass

The ICD-10-CM code for liver mass is R16.0 (Hepatomegaly, not elsewhere classified).

Within R16 (Hepatomegaly and splenomegaly, not elsewhere classified), R16.0 is specifically for Hepatomegaly, not elsewhere classified. Related codes cover splenomegaly, not elsewhere classified (R16.1) and Hepatomegaly with splenomegaly, not elsewhere classified (R16.2).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

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) and DRG 443 (Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis without CC/MCC, relative weight 0.6885), in MDC 07 (Diseases and Disorders of the Hepatobiliary System and Pancreas), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
