Infections of cervix in pregnancy, unspecified trimester

This code signifies a bacterial, viral, fungal, or parasitic infection affecting the uterine cervix during any stage of pregnancy. It indicates that the specific trimester of the pregnancy at the time of diagnosis is not documented or is unknown. This condition can potentially impact both maternal and fetal health.

Use this code when documentation confirms a cervical infection in a pregnant patient, but the medical record does not specify the trimester. This often occurs when the exact gestational age is not yet precisely determined or is simply omitted from the diagnostic statement. Supporting documentation would include physician notes indicating "cervicitis in pregnancy" or "cervical infection, pregnant."

• Only use this code when the trimester is truly unspecified; if the trimester is known, a more specific O23.5- subcategory should be used.
• Always code the specific type of infection (e.g., N72 for cervicitis) as an additional diagnosis if known.
• Do not use this code if the infection is a sexually transmitted infection (STI) with a specific code in Chapter A, B, or O98.
