About R16.2

R16.2 is the ICD-10-CM diagnosis code for Hepatomegaly with splenomegaly, not elsewhere classified. It belongs to category R16 (Hepatomegaly and splenomegaly, not elsewhere classified), block R10-R19 (symptoms and signs involving the digestive system and abdomen) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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

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.

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 789.1 (Hepatomegaly) and 789.2 (splenomegaly).
