Viral hepatitis (B15-B19) ICD-10-CM
The B15–B19 section covers viral hepatitis with 31 ICD-10-CM diagnosis codes, of which 23 are billable in fiscal year 2027. The section is organized into the 5 code ranges listed below.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the B15–B19 Code Range
Viral hepatitis is inflammation of the liver caused by a virus. These categories separate acute infections, chronic infections, and cases without an acute or chronic designation.
B15 covers acute hepatitis A and separates cases by whether hepatic coma is present. Hepatic coma means liver-related coma. B16 covers acute hepatitis B and distinguishes both hepatic coma and the presence of delta-agent, or hepatitis D.
B17 includes other acute infections, such as hepatitis C, hepatitis E, and delta infection in a hepatitis B carrier. B18 covers chronic viral hepatitis, separating hepatitis B with or without delta-agent from hepatitis C and other cases. B19 covers viral hepatitis without an acute or chronic designation, with subdivisions for hepatitis B, hepatitis C, and hepatic coma.
