ICD-10 code for D hepatitis

The ICD-10-CM code for D hepatitis is B16.1 (Acute hepatitis B with delta-agent without hepatic coma). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on B16.1.

Within B16, choose B16.1 (with delta-agent without hepatic coma) only when documentation doesn't support a more specific option: with delta-agent with hepatic coma (B16.0), without delta-agent with hepatic coma (B16.2) and without delta-agent and without hepatic coma (B16.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

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), DRG 443 (Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis without CC/MCC, relative weight 0.6885), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 07 (Diseases and Disorders of the Hepatobiliary System and Pancreas) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
