Matern care for or susp placntl insuff, third tri, unsp

This code signifies ongoing maternal care during the third trimester for a pregnancy complicated by known or suspected placental insufficiency. This condition refers to the placenta's inability to adequately provide nutrients and oxygen to the fetus, potentially leading to fetal growth restriction or other adverse outcomes.

Apply this code when the patient is in her third trimester and receiving monitoring or interventions due to a diagnosis or strong suspicion of placental insufficiency. Documentation should clearly state the trimester and the reason for care, such as abnormal Doppler studies, fetal growth concerns, or a history of placental issues in previous pregnancies.

• Ensure the documentation explicitly states "third trimester" for accurate code assignment.
• Do not use this code if the placental insufficiency is definitively ruled out or if the care is for a different trimester.
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is related to the management of the placental insufficiency (e.g., fetal surveillance, antenatal testing).
