Unsp maternal infec/parastc disease comp preg, unsp tri

This code signifies a maternal infectious or parasitic disease that is complicating a pregnancy, where the specific type of infection is not documented. It indicates that the infection is having an adverse effect on the pregnancy, but the precise nature of the pathogen or the resulting condition is unknown. The trimester of pregnancy is also not specified in the medical record.

Use this code when the medical record clearly states that an infectious or parasitic disease is complicating the pregnancy, but lacks specific details regarding the type of infection (e.g., "maternal infection complicating pregnancy"). This code is appropriate when the documentation does not specify the trimester of pregnancy. It should be used as a last resort when more specific codes are unavailable.

• Avoid using this code if the specific type of infection (e.g., urinary tract infection, influenza) is documented; instead, code the specific infection along with an appropriate O-code for the complication.
• Always strive for greater specificity regarding the type of infection and the trimester of pregnancy if documented.
• This code should be sequenced as the principal diagnosis if the infection is the primary reason for the encounter, followed by codes for any specific manifestations if known.
