ICD-10 code for Cholangioma

The ICD-10-CM code for Cholangioma is D13.4 (Benign neoplasm of liver).

Within D13 (benign neoplasm of other and ill-defined parts of digestive system), D13.4 is specifically for benign neoplasm of liver. Related codes cover esophagus (D13.0), stomach (D13.1), duodenum (D13.2), other and unspecified parts of small intestine (D13.3), extrahepatic bile ducts (D13.5), pancreas (D13.6), endocrine pancreas (D13.7) and ill-defined sites within the digestive system (D13.9).

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.
