Specific Coding for Other acute viral hepatitisOverview

Non-specific codes like B17 require more characters. Use one of these billable codes instead:

  • Use B17.0 for Acute delta-(super) infection of hepatitis B carrier

  • B17.1 for Acute hepatitis C

  • Use B17.10 for Acute hepatitis C without hepatic coma

  • Use B17.11 for Acute hepatitis C with hepatic coma

  • Use B17.2 for Acute hepatitis E

  • Use B17.8 for Other specified acute viral hepatitis

  • Use B17.9 for Acute viral hepatitis, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to B17: its own notes plus those printed at block B15-B19 and Chapter 1. A note printed at a category, block or chapter applies to every code under it.

From Chapter 1 (A00-B99) Certain infectious and parasitic diseases applies to 1,068 codes
  • diseases generally recognized as communicable or transmissible

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

From Block B15-B19 Viral hepatitis applies to 23 codes
  • sequelae of viral hepatitis (B94.2)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Block B15-B19 Viral hepatitis applies to 23 codes

Patient EducationClinical

Hepatitis

Hepatitis is inflammation of the liver. Inflammation is swelling that happens when tissues of the body are injured or infected. It can damage your liver. This swelling and damage can affect how well your liver functions.

Questions About B17Overview

What is the ICD-10 code for other acute viral hepatitis?

B17 is the ICD-10-CM category for other acute viral hepatitis, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is B17 (Other acute viral hepatitis) a billable code?

No. This is a category header that groups the codes for other acute viral hepatitis, and headers cannot be submitted on claims. Claims for other acute viral hepatitis need a more specific code from this category, such as B17.0, B17.10, and B17.11.

Can B17 be reported with B94.2?

Not as a rule. The Excludes1 note at block B15-B19, which applies to B17, lists "sequelae of viral hepatitis (B94.2)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
