Coding guidance (WHO 2019)
Note: This category includes conditions which complicate the pregnant state, are aggravated by the pregnancy or are a main reason for obstetric care and for which the Alphabetical Index does not indicate a specific rubric in Chapter XV. Use additional code, if desired, to identify specific condition. Excl.: infectious and parasitic diseases (O98.-) injury, poisoning and certain other consequences of external causes (S00-T98) when the reason for maternal care is that the condition is known or suspected to have affected the fetus (O35-O36)
