Viral hepatitis complicating pregnancy, first trimester

This code signifies the presence of viral hepatitis in a pregnant patient during her first trimester. It indicates that the hepatitis is considered a complication of the pregnancy, potentially impacting both maternal and fetal health. This includes acute or chronic forms of viral hepatitis (e.g., Hepatitis A, B, C, D, E).

Apply this code when documentation clearly states a diagnosis of viral hepatitis occurring in a pregnant patient who is in her first trimester (up to the end of the 13th week of gestation). Supporting documentation should include a confirmed diagnosis of viral hepatitis and a clear indication of the gestational period.

• Always sequence this code as a secondary diagnosis following the appropriate pregnancy code (e.g., O09.- for supervision of normal pregnancy).
• Ensure the medical record specifies "first trimester" to justify the use of the .411 subcategory. If the trimester is not specified, query the provider.
• Do not use this code for viral hepatitis that is not complicating the pregnancy; instead, use the appropriate B15-B19 codes.
