B17.8Other specified acute viral hepatitis

B17.8 is the ICD-10-CM diagnosis code for other specified acute viral hepatitis. It belongs to category B17 (other acute viral hepatitis), block B15-B19 (viral hepatitis) and chapter 1 (certain infectious and parasitic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within B17, choose B17.8 (Other specified acute viral hepatitis) only when documentation doesn't support a more specific option: acute delta-(super) infection of hepatitis B carrier (B17.0), acute hepatitis C (B17.1), acute hepatitis E (B17.2) and acute viral hepatitis, unspecified (B17.9).

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.

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 070.49 (other specified viral hepatitis with hepatic coma) and 070.59 (other specified viral hepatitis without mention of hepatic coma).
