B19.10 — Unspecified viral hepatitis B without hepatic coma
Is B19.10 billable?
Yes, but B19.10 is an unspecified code. B19.10 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, B19.10 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting B19.10 — the more specific alternatives are listed below.

Which MS-DRGs does B19.10 group to?
B19.10 sits in MDC 07 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 441Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis with MCCmedical
- 442Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis with CCmedical
- 443Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis without CC/MCCmedical
As a secondary diagnosis, B19.10 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from B15-B19
The conditions below can never be reported together with B19.10 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- sequelae of viral hepatitis (B94.2)
Use additional code — inherited from Chapter 1
Report an additional code alongside B19.10 to fully describe the condition. B19.10 is sequenced first.
- code to identify resistance to antimicrobial drugs (Z16.-)
Excludes2 — not included here — inherited from Chapter 1
The conditions below are not part of B19.10, but a patient may have both at the same time. When documentation supports it, B19.10 and the excluded code may both be reported.
- carrier or suspected carrier of infectious disease (Z22.-)
- certain localized infections - see body system-related chapters
- infectious and parasitic diseases complicating pregnancy, childbirth and the puerperium (O98.-)
- infectious and parasitic diseases specific to the perinatal period (P35-P39)
