Viral hepatitis complicating pregnancy, third trimester

This code signifies the presence of a viral hepatitis infection occurring during the third trimester of a pregnancy. It indicates that the hepatitis is considered a complication impacting the maternal health during this specific gestational period.

Use this code when a pregnant patient in her third trimester is diagnosed with any form of viral hepatitis (e.g., Hepatitis A, B, C, D, E) that is documented as complicating the pregnancy. Supporting documentation would include physician notes explicitly stating the viral hepatitis diagnosis, the trimester of pregnancy, and its impact or presence as a complication.

• Always sequence this code as a primary diagnosis when the viral hepatitis is the main reason for the encounter, or as a secondary diagnosis when it is a co-morbidity.
• Ensure the medical record clearly specifies "third trimester" for accurate code assignment; otherwise, an unspecified trimester code (O98.419) may be more appropriate.
• Do not use this code if the viral hepatitis is resolved prior to the third trimester or if it is not documented as complicating the pregnancy.
