About the B16 Code Range
Acute hepatitis B is a new infection with the hepatitis B virus. It belongs to the viral hepatitis group.
The subdivisions of B16 separate cases with delta-agent (hepatitis D) from those without it. Each group then separates cases with hepatic coma, a liver-related coma, from those without it.
With delta-agent, B16.0 has hepatic coma and B16.1 does not. Without delta-agent, B16.2 has hepatic coma and B16.9 does not.
