Human immunodef virus disease comp pregnancy, unsp trimester

This code signifies a pregnant patient diagnosed with human immunodeficiency virus (HIV) disease, where the specific trimester of pregnancy is not documented. It indicates that the HIV infection is considered a complication of the pregnancy itself, requiring careful management throughout gestation.

Apply this code when a pregnant patient has a confirmed diagnosis of HIV disease, and the medical record does not specify which trimester the complication is being reported for. This is appropriate for initial encounters or when the trimester is unknown or not relevant to the current encounter's focus.

• Always sequence this code as a secondary diagnosis, following the code for the obstetric condition (e.g., O99.89 for other specified diseases and conditions complicating pregnancy).
• If the trimester is known, use the more specific O98.711, O98.712, or O98.713 codes.
• Do not use this code if the HIV status is merely incidental and not documented as complicating the pregnancy.
