Cytomegaloviral hepatitis

This code identifies inflammation of the liver caused by an active cytomegalovirus (CMV) infection. It signifies hepatic involvement as a manifestation of systemic CMV disease.

Assign this code when medical record documentation confirms hepatitis due to cytomegalovirus. This typically requires laboratory confirmation of CMV infection (e.g., positive PCR, serology) alongside evidence of liver inflammation (e.g., elevated liver enzymes, biopsy findings).

• Always confirm the causal link between CMV and hepatitis; do not assume based on co-occurrence.
• Code any associated manifestations of CMV (e.g., pneumonitis, colitis) separately.
• Consider an additional code for the underlying condition if the CMV infection is opportunistic (e.g., HIV, transplant recipient).
