- O35: Maternal care for known or suspected fetal abnormality and damage
In simple words: This code is used when a mother receives medical care because of a problem with her baby during pregnancy.This could be because of a suspected birth defect or injury to the baby. The doctor's focus is on the mother's health in relation to the baby's condition.
This code is used for maternal care related to known or suspected fetal abnormalities or damage.It includes maternal conditions associated with the fetal issues, leading to hospitalization, other obstetric care, or termination of pregnancy.The code encompasses various fetal abnormalities, requiring appropriate 7th character specification to identify the affected fetus (if multiple fetuses are involved).Excludes encounters where suspected maternal and fetal conditions are ruled out.
Example 1: A pregnant woman undergoes genetic testing revealing a chromosomal abnormality in the fetus.Code O35 is used to record the maternal care provided due to this finding., A pregnant woman presents with a suspected neural tube defect in the fetus.Ultrasound and further evaluations are performed, and O35 is used to document maternal care related to this suspected fetal abnormality., A pregnant woman is admitted to hospital due to complications related to a known fetal abnormality such as a heart defect.O35 along with further specific codes would accurately reflect the reasons for care.
Detailed medical records including genetic test results, ultrasound images, fetal monitoring data, consultation notes, and any procedures performed related to the fetal abnormality or damage.Documentation should clearly link the maternal care to the identified or suspected fetal problem.
** Code O35 should only be used on maternal records; it is never to be used on newborn records.This code is for conditions related to or aggravated by the pregnancy, childbirth, or puerperium (maternal or obstetric causes).
