Human immunodef virus disease comp preg, first trimester

This code signifies a pregnant patient in her first trimester who has a confirmed diagnosis of HIV disease. It indicates that the HIV infection is actively complicating the current pregnancy, requiring specific management and monitoring.

Apply this code when documentation clearly states a patient is HIV positive and pregnant, specifically within the first trimester. This code is appropriate for encounters where the patient's HIV status is impacting or being managed in relation to her pregnancy.

• Always sequence this code first when the reason for the encounter is related to the HIV complicating pregnancy.
• Requires documentation of both HIV disease and the first trimester of pregnancy.
• Do not use for asymptomatic HIV status in pregnancy; use Z21 with an O98.7- code for complications.
