B16.0

What This Code Means

This is a severe acute infection of the liver caused by both hepatitis B and delta viruses occurring together, where the patient has developed hepatic coma (a serious condition where liver failure causes loss of consciousness). This is a life-threatening condition requiring immediate medical intervention.

Coding Tips

• •This code should only be used when both hepatitis B and delta-agent (hepatitis D) are confirmed present with documented hepatic coma; do not use if coma is absent
• •Verify documentation clearly states 'acute' hepatitis B with delta-agent and hepatic coma, as chronic variants and cases without coma require different codes
