About the O9A Code Range
Cancer, injuries, poisoning, and abuse can complicate pregnancy, childbirth, or the period after childbirth.
The branches separate cancer (O9A.1); injury, poisoning, and other consequences of external causes (O9A.2); and physical (O9A.3), sexual (O9A.4), or psychological abuse (O9A.5). Each branch distinguishes pregnancy, childbirth, and the period after childbirth. Pregnancy subdivisions separate the first, second, third, and unspecified trimesters.
