ICD-10 code for bilirubin metabolism disorder

The ICD-10-CM code for bilirubin metabolism disorder is E80.7 (Disorder of bilirubin metabolism, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on E80.7.

Within E80, choose E80.7 (Disorder of bilirubin metabolism, unspecified) only when documentation doesn't support a more specific option: hereditary erythropoietic porphyria (E80.0), porphyria cutanea tarda (E80.1), other and unspecified porphyria (E80.2), defects of catalase and peroxidase (E80.3), Gilbert syndrome (E80.4), Crigler-Najjar syndrome (E80.5) and other disorders of bilirubin metabolism (E80.6).

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.
