About coding liver cyst
The ICD-10-CM code for liver cyst is K76.89 (Other specified diseases of liver). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K76.89.
Within K76.8, choose K76.89 (Other specified diseases of liver) only when documentation doesn't support a more specific option: Hepatopulmonary syndrome (K76.81), hepatic encephalopathy (K76.82) and intestinal failure-associated liver disease (K76.83).
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.
